C# - Programmatically Refreshing A Datagrid?

Jul 6, 2010

I have an asp.net webpage that does a bunch of (slow, hence the problem) calculations and dumps them all into a datagrid in a webpage. I would like to be able to have the page show partial results.

I have figured out how to re-update the grid every time a row is done, but the page still doesn't display the results until all the calculations are complete. Does anyone know a call from asp.net that can tell the page to refresh itself?

p.s. the update function I am currently using is as follows:

private void updateDisplay(DataTable outputTable)
{
if (outputTable.Rows.Count > 0)
{
PlaceHolder1.Controls.Clear();

[Code]....

C# - Add TemplateColumn Of CheckBoxes To DataGrid Programmatically

Jul 19, 2010

in my procedure in code-behind I am trying to create a DataGrid with autoGenerateColumns = true :

DataGrid NewDg = new DataGrid();
NewDg.AutoGenerateColumns = true;
NewDg.Width = Unit.Percentage(100.00);
NewDg.DataSource = ds;
NewDg.DataBind();

I need to also add another column (TemplateColumn maybe) of CheckBoxes to this Grid.Do you know how to do that??

I have tried that:

TemplateColumn t = new TemplateColumn();
CheckBox c = new CheckBox();
t.ItemTemplate = (ITemplate)c;
NewDg.Columns.Add(t);

I get the following exception trace:

System.InvalidCastException: Unable to cast object of type 'System.Web.UI.WebControls.CheckBox' to type 'System.Web.UI.ITemplate'. at Default2.DataGrid1_ItemDataBound(Object sender, DataGridItemEventArgs e) in c:UserssaherDocumentsTreeTestTreeDemoDefault2.aspx.cs:line 116 at System.Web.UI.WebControls.DataGrid.OnItemDataBound(DataGridItemEventArgs e) at System.Web.UI.WebControls.DataGrid.CreateItem(Int32 itemIndex, Int32 dataSourceIndex, ListItemType itemType, Boolean dataBind, Object dataItem, DataGridColumn[] columns, TableRowCollection rows, PagedDataSource pagedDataSource) at System.Web.UI.WebControls.DataGrid.CreateControlHierarchy(Boolean useDataSource) at System.Web.UI.WebControls.BaseDataList.OnDataBinding(EventArgs e) at System.Web.UI.WebControls.BaseDataList.DataBind() at Default2.BindData() in c:UserssaherDocumentsTreeTestTreeDemoDefault2.aspx.cs:line 44

UpdatePanel Not Refreshing In Accordion?

Mar 23, 2010

I'm using MS AJAX's accordion control. It works fine normally, but I can't seem to get it to work with an UpdatePanel. My layout is like this:

<div id="accordion">
<div><a href="#">Header1</a></div>
<div class="acc_content">
<asp:UpdatePanel ID="UpdatePanel1" runat="server" UpdateMode="Conditional" >
<ContentTemplate>
<asp:button id="btnToggle" runat="server" text="toggle"/>
//my repeater contents go here. The buttons within the repeater cause a postback, but changes cannot be seen unless the page is manually refreshed (since the updatepanel doesn't refresh)
</ContentTemplate>
<Triggers>
<asp:AsyncPostBackTrigger ControlID="btnToggle" EventName="click" />
<asp:AsyncPostBackTrigger ControlID="btnAdd" EventName="click" /> //this button is outside the updatepanel
</ContentTemplate>
</Triggers>
</asp:UpdatePanel>
</div>
<div><a href="#">Header 2 </a></div>
<div class="acc_content">
Content of the second pane
</div>
</div>

There are postbacks occurring when I click the buttons, but the updatepanel never refreshes or updated. I tried adding UpdatePanel1.Update() in the code-behind for each postback event, but no luck. Any ideas as to why this is happening?

C# - Gridview Rowcommand After Refreshing?

May 31, 2010

protected void GridView1_RowCommand(object sender, GridViewCommandEventArgs e)
{
GridViewRow row = ((e.CommandSource as Control).NamingContainer as GridViewRow);

Row from the above code gives the values from the gridview before the gridview is refreshed/updated.
