Prevent RowChecker from checking rows that are not expanded in a hierarchical grid

mlacy1358 — Fri, 13 Sep 2013 17:12:55 GMT

We are using the latest version of the Intersoft WebGrid. We have a self-referencing hierarchical grid that has RowChecker enabled so there is a "check all" check box in the column header of the checkbox column that when checked will check all of the rows in the grid. The issue is that this is a hierarchical grid and so at any time, one folder may be expanded showing the child rows but all the other parent rows are collapsed (so their child rows are not visible). When the RowChecker "check all" checkbox in the column header is selected, all the rows are checked, even those that are collapsed and so are not visible. Is there a way to tell the RowChecker to only check the child rows that are visible and to not check the child rows that are in a collapsed state and so are not visible?

Can't update rowChecker in any events that occur after client binding

We have a grid (version 7.0.7200.533) that is bound on the client through web services. This grid contains a rowChecker column that allows users to select items in the grid.

The application mimics a file management system, which allows the user to navigate a tree folder structure. Each time a different folder is selected, the grid is refreshed with information related to that folder.

As the user selects items, we persist information about the selected items in a separate window so that the user can select multiple items from separate folders.

When the user navigates to a folder, we use the OnInitializeRow client event to show the user any items that they had previously selected in that folder.

This has worked for a very long time, but in the recent past we updated to a service release (not exactly sure which one broke it) that caused this to stop working. No matter what value we set (the cell value directly, the Check property on the row, or the Check() method on the row), the RowChecker cell is not set.

We have also tried hooking the OnPostRender and OnDataBound methods with an equal amount of failure.

Or final hack at this issue was to collect the list of rows to be checked in OnInitializeRow, then in OnPostRender, set a timeout with code to process the list of rows and call Check() on each of them. This works, but is a dreadful hack.

Is there any way to get back to the previous behavior?

Hi Team,

I have webgrid with rowchecker on it, and I have property AllowExport yes. What I want is when I do export to let say excel file, I want only selected data (picked from rowchecker) to be export. Could you guys give me a simple sample that show how it works? Immediate response will be appreciated.

Best Regards,

WebGrid RowChecker column not persisting on postback so GetCheckedRows is always empty

neil.turner@ntd.co.uk — Tue, 14 Jun 2011 09:34:18 GMT

I have a Webgrid with a RowChecker and a button to run an action on the checked rows.

However getCheckedRows always returs empty and on clickikg the button all the checkboxes in the grid are cleared.

I have coopied the code posted on this forum before but it still returns 0. I am using WebGrid 7

This is the op of my grid

<ISWebGrid:WebGrid ID="wgArchive" runat="server" DataSourceID="sdsAppointments">

<ISWebGrid:WebGridColumn ColumnType="CheckBox" IsRowChecker="True" Name="RowChecker">

</ISWebGrid:WebGridColumn>

And this is the code the button runs

protected void btnArchive_Click(object sender, EventArgs e)

{

lbMsg.Text = wgArchive.RootTable.Rows.Length.ToString() + " rows affected ";

foreach (string keyValue in wgArchive.RootTable.GetCheckedRows())

{

lbMsg.Text += keyValue + " ; \n";

}
