Iterate Gridview to find greatest value using Javascript or jQuery - javascript

I have a gridview and scenario is: once someone deletes a row, it checks if NOTIF_RECIP_SEQ_NBR is maximum or not. If yes then it deletes that row else give a popup.
So basically once someone click on delete, it gets the NOtif_recip_Id of that row and iterates through Gridview to see if NOTIF_RECIP_SEQ_NBR of any row corresponding to that NOTIF_RECIP_ID is greater or not.
Question is It possible at client side? I did it with server side but I don't think that's a good way when I have all data on client side itself.
Please help. I tried multiple ways with Javascript but no use.

for (i = 1; i < grid.rows.length-1; i++)
{
//here I want code to iterate and compare value.Is it possible?
alert("You must select an answer for all columns if Pivot is yes")

how to add 'More...' button on a column of Gridview by jquery or javascript

I have a TemplateField in Gridview which may be very long. I want to cut or trim it if it has more than 100 characters and instead replace a button "more..." that if user clicks on it, the whole text will be shown by jquery or javascript.
this is my GridView:
<asp:GridView ID="GVProjects" runat="server" CssClass="GVAdmin">
<Columns>
<asp:TemplateField HeaderText=" Info ">
<ItemTemplate>
<asp:Label ID="labelinfo" runat="server" CssClass="GVAdmin"
Text='<%# Eval("Information") %>' ></asp:Label>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
And I want to have something like this:
You can do this by below example :-
<asp:TemplateField HeaderText="Description">
<ItemTemplate>
<asp:Label ID="lblDescription" runat="server"
Text='<%# Limit(Eval("Description"),40) %>'
Tooltip='<%# Eval("Description") %>'>
</asp:Label>
<asp:LinkButton ID="ReadMoreLinkButton" runat="server"
Text="Read More"
Visible='<%# SetVisibility(Eval("Description"), 40) %>'
OnClick="ReadMoreLinkButton_Click">
</asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
And for code-behind
protected bool SetVisibility(object desc, int maxLength)
{
var description = (string)desc;
if (string.IsNullOrEmpty(description)) { return false; }
return description.Length > maxLength;
}
protected void ReadMoreLinkButton_Click(object sender, EventArgs e)
{
LinkButton button = (LinkButton)sender;
GridViewRow row = button.NamingContainer as GridViewRow;
Label descLabel = row.FindControl("lblDescription") as Label;
button.Text = (button.Text == "Read More") ? "Hide" : "Read More";
string temp = descLabel.Text;
descLabel.Text = descLabel.ToolTip;
descLabel.ToolTip = temp;
}
protected string Limit(object desc, int maxLength)
{
var description = (string)desc;
if (string.IsNullOrEmpty(description)) { return description; }
return description.Length <= maxLength ?
description : description.Substring(0, maxLength)+ "<a>...</a>";
}
Edited :-
To use only javascript you can add/call a java-script function from tag and can remove "OnClick="ReadMoreLinkButton_Click"" from itemtemplate.
Upon #Anand Systematix's answer you can modify this to use with jquery
<asp:TemplateField HeaderText="Description">
<ItemTemplate>
<asp:Label ID="lblDescription" runat="server"
Text='<%# Limit(Eval("Description"),40) %>'
Tooltip='<%# Eval("Description") %>'>
</asp:Label>
</ItemTemplate>
</asp:TemplateField>
Code behind to limit string
protected string Limit(object desc, int maxLength)
{
var description = (string)desc;
if (string.IsNullOrEmpty(description)) { return description; }
return description.Length <= maxLength ?
description : description.Substring(0, maxLength)+ "<a class='lnkReadMore' href='javascript:void(0);'>...</a>";
}
jquery for handling lnkReadMore click
$('.lnkReadMore').click(function(e)
{
var labelElement = $(this).closest("[id*='lblDescription']")
var fullText = $(labelElement).attr("title");
$(labelElement).text(fullText);
});

Get sum of gridview textboxes values and show total in label using javascript

I have in my application a grid-view in which a number of textboxes as template field, which can be incremented.When i enter some value in first textbox the sum of all textbox should be shown in Label. I have tried to use the below code but it didn't work.
JavaScript
<script type="text/javascript">
function calculate() {
var txtTotal = 0.00;
$(".calculate").each(function (index, value) {
var val = value.value;
val = val.replace(",", ".");
txtTotal = MathRound(parseFloat(txtTotal) + parseFloat(val));
});
document.getElementById("<%= lbltotal.ClientID %>").value = txtTotal.toFixed(2);
}
function MathRound(number) {
var result = Math.round(number * 100) / 100;
return result;
}
</script>
GridView
<asp:GridView ID="GridView1" runat="server" ShowFooter="true" AutoGenerateColumns="false">
<Columns>
<asp:BoundField DataField="RowNumber" HeaderText="Row Number" />
<asp:BoundField DataField="Description" HeaderText="Item Description" />
<asp:TemplateField HeaderText="Amount">
<ItemTemplate>
<asp:TextBox ID="txtamount" onkeyup="calculate();" CssClass="calculate" runat="server" Text=""></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
label
<asp:Label ID="lbltotal" runat="server" Text="" ForeColor="Green"></asp:Label>
Use this snippet. It adds an keyup listener to every TextBox in GridView1. Then it loops all the TextBoxes and adds the values and put the total in Label1
<script type="text/javascript">
var total = 0;
$(document).ready(function () {
$('#<%= GridView1.ClientID %> input[type="text"]').keyup(function () {
$('#<%= GridView1.ClientID %> input[type="text"]').each(function () {
if ($(this).val() != "") {
total += parseFloat($(this).val());
}
});
document.getElementById("<%= Label1.ClientID %>").innerHTML = total.toFixed(2);
});
});
</script>

Search not working on Gridview

I have Implemented the Search on gridview for columns from this
link. I implemented as per my requirement.But it is not working for me. Please see the code for your reference:-

<HeaderTemplate>
<asp:Button ID="btnInsertRecord" runat="server" Text="Add" CommandName="Insert" />
</HeaderTemplate>
<HeaderStyle Width="15%"></HeaderStyle>
</asp:TemplateField>
</Columns>
</asp:GridView>
Also see the JS script
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.8.3/jquery.min.js"></script>
<script type="text/javascript" src="js/quicksearch.js"></script>
<script type="text/javascript">
$(function () {
$('.form-control').each(function (i) {
$(this).quicksearch("[id*=grdCSRPageData] tr:not(:has(th))", {
'testQuery': function (query, txt, row) {
return $(row).children(":eq(" + i + ")").text().toLowerCase().indexOf(query[0].toLowerCase()) != -1;
}
});
});
});
</script>
Also see the code behind for your ref:-
protected void grdCSRPageData_DataBound(object sender, EventArgs e)
{
GridViewRow row = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Normal);
for (int i = 0; i < grdCSRPageData.Columns.Count; i++)
{
TableHeaderCell cell = new TableHeaderCell();
TextBox txtSearch = new TextBox();
txtSearch.Attributes["placeholder"] = grdCSRPageData.Columns[i].HeaderText;
txtSearch.CssClass = "form-control";
cell.Controls.Add(txtSearch);
row.Controls.Add(cell);
}
grdCSRPageData.HeaderRow.Parent.Controls.AddAt(1, row);
}
Changes for the grid
protected void grdUser_DataBound(object sender, EventArgs e)
{
GridViewRow row = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Normal);
for (int i = 0; i < grdUser.Columns.Count; i++)
{
TableHeaderCell cell = new TableHeaderCell();
TextBox txtSearch = new TextBox();
txtSearch.Attributes["placeholder"] = grdUser.Columns[i].HeaderText;
txtSearch.CssClass = "form-control HaydaBre";
if (grdUser.Columns[i].HeaderText != "Action" && grdUser.Columns[i].HeaderText != "" && grdUser.Columns[1].HeaderText != "Select") // && grdUser.Columns[i].HeaderText != "" && grdUser.Columns[i].HeaderText != null && grdUser.Columns[i].HeaderText != "Select")
{
cell.Controls.Add(txtSearch);
}
row.Controls.Add(cell);
}
grdUser.HeaderRow.Parent.Controls.AddAt(1, row);
}
When I add the HeaderText != Select. It stops working for the first column, but it works for the other column
There are a lot of elements with form-control class. So can you change your C# code to be:
protected void grdCSRPageData_DataBound(object sender, EventArgs e)
{
GridViewRow row = new GridViewRow(0, 0, DataControlRowType.Header, DataControlRowState.Normal);
for (int i = 0; i < grdCSRPageData.Columns.Count; i++)
{
TableHeaderCell cell = new TableHeaderCell();
TextBox txtSearch = new TextBox();
txtSearch.Attributes["placeholder"] = grdCSRPageData.Columns[i].HeaderText;
txtSearch.CssClass = "form-control HaydaBre";
cell.Controls.Add(txtSearch);
row.Controls.Add(cell);
}
grdCSRPageData.HeaderRow.Parent.Controls.AddAt(1, row);
}
and your JS code to be:
<script type="text/javascript">
$(function () {
$('.HaydaBre').each(function (i) {
$(this).quicksearch("[id*=grdCSRPageData] tr:not(:has(th))", {
'testQuery': function (query, txt, row) {
return $(row).children(":eq(" + i + ")").text().toLowerCase().indexOf(query[0].toLowerCase()) != -1;
}
});
});
});
</script>

</script>
You need to convert grid view row cell control to the appropriate control explicitly.
access like this ((Textbox)(GridView1.Rows[i].Cells[4].Controls[0]).Text for your #QtyOrder
and ((Label)(GridView1.Rows[i].Cells[5].Controls[0]).Text for #Total.
OR
(GridView1.Rows[i].FindControl("txtQty") as TextBox).Text

validate dropdown box if checkbox is checked using javascript

My requirement is that if check-box is checked then you have to select something from the dropdown box. I have multiple rows in the gridview so i am only requiring that you have to make a selection from the dropdown if you select the checkbox.
function validateDDL() {
var flag = true;
var dropdowns = new Array(); //Create array to hold all the dropdown lists.
var gridview = document.getElementById('<%=gvSearch.ClientID%>'); //GridView1 is the id of ur gridview.
dropdowns = gridview.getElementsByTagName('Select'); //Get all dropdown lists contained in GridView1.
for (var i = 0; i < dropdowns.length; i++) {
if (dropdowns.item(i).value == 'Select') //If dropdown has no selected value
{
flag = false;
break; //break the loop as there is no need to check further.
}
}
if (!flag) {
dropdowns[i].focus();
alert('Please select a Project Role from the dropdown box. Thanks');
}
return flag;
}
</script>
