VS 2010 - GridView With CheckBox In Each Row - Button To Select / Deselect All And Not Postback
Aug 12, 2011
I have a gridview with a checkbox in each row for selecting. I want to have a button which will select all/deselect all and not post back.
I first implemented this with a link and it works perfectly, but I don't like how it looks.
Code:
<a href="#" onclick="javascript:sel();">Select/deselect all</a>
Code:
<script type="text/javascript">
isSelected = false;
function sel() {
var frm = document.forms[0];
isSelected = !isSelected;
[Code] ....
So now I have a button that I want to rig up to execute this javascript. Which I believe would be done this way:
Code:
<asp:Button ID="btnSelectAllSummary" runat="server" Text="Select All" OnClientClick="javascript:sel()" />
But it is posting back. How do I prevent the postback and have it execute on the client?

I am using a gridview where there are 6 cols and the last col consist of checkboxes. I wrote a code such that all the checkboxes in the col are selected or deselected at once by clicking the header checkbox. Now the issue is since I am using paging for the Gridview, once I select the checkboxes in the last col and go for the next page and come back to the previous page the checkboxes are deselected. I want to keep the checkboxes selected even after pagination.

I have a gridview which is bound to a sqldtatasource. The gridview has 3 columns and a select button. The data in the gridview pulls up just fine when I run the application and the first record is selected.
However when I select one of the other records, the gridview will not select it. The postback occurs and it remains on the first record. Here is code for my gridview and the sqldatasource:

I am having to create a GridView 100% in C# CodeBehind. I have it selecting a row and posting back using this code:
void dataGrid_ItemCreated(object sender, DataGridItemEventArgs e)
{
if (e.Item.ItemType == ListItemType.AlternatingItem ||
e.Item.ItemType == ListItemType.Item)
{
e.Item.Attributes.Add("onmouseover",
"this.style.backgroundColor='beige';this.style.cursor='pointer'");
e.Item.Attributes.Add("onmouseout",
"this.style.backgroundColor='#FFFFFF';");
e.Item.Attributes.Add("onclick", "javascript:__doPostBack" +
"('_ctl0$DataGrid1$_ctl" +
((Convert.ToInt32(e.Item.ItemIndex.ToString())) + 2) +
"$_ctl0','')");
}
}
This does post back but then how do I get the ID of the row the user clicked on?

In design time I created a Gridview and a delete button in a page test.aspx:
[Code]....
The program stopped at statement "if ((row.Cells[COL_INDEX_SELECTED].Controls[0] as CheckBox).Checked)",
because it cannot find the checkbox created before.
I tried to shift all the code in Page_Load to Page_Init, but the ticked checkboxes are still lost.
I could find the ticked checkboxes names in its request object parameters(this.Request.Params.AllKey) if I setup a breakpoint on the error statement.
Does anyone konw what's happening and how to retrieve the selected rows?

I have a gridview which is ShowSelectButton = "False"
I use
e.Row.Attributes.Add("onclick", Page.ClientScript.GetPostBackEventReference(sender, "Select$" & e.Row.RowIndex.ToString))
to select a gridviewrow but it causes a postback whenever I select a row. Is there a way to allow selecting a gridview row which will not cause a postback??
