Hi,
Can someone guide me on how to generate hierarchical grids dynamically from code behind based on certain business rules that will reside in separate tabs of a RadTabStrip. The grids should be fully editable and ajaxified. The grids will bind to different data sources based on the rules.

Thanks.

‚Äč for (int i = 0; i < 5; i++)
{

RadGrid RadGrid1 = new RadGrid();
if (i == 0)
RadGrid1.DataSource = crList0;
else RadGrid1.DataSource = crList1;
RadGrid1.DataBind();
RadGrid1.MasterTableView.DataKeyNames = new string[] { "FriendlyKey" };
RadGrid1.AllowPaging = true;
RadGrid1.AutoGenerateColumns = false;
RadGrid1.AutoGenerateEditColumn = true;
RadGrid1.Skin = "Metro";
RadGrid1.AllowPaging = false;
RadGrid1.ItemDataBound += new GridItemEventHandler(RadGrid1_ItemDataBound);
RadGrid1.RenderMode = RenderMode.Lightweight;

GridBoundColumn boundColumn1;
boundColumn1 = new GridBoundColumn();
boundColumn1.DataField = "FriendlyKey";
boundColumn1.HeaderText = "FriendlyKey";
boundColumn1.UniqueName = "FriendlyKey";
RadGrid1.MasterTableView.Columns.Add(boundColumn1);
GridBoundColumn boundColumn2;
boundColumn2 = new GridBoundColumn();
boundColumn2.DataField = "ApplicationName";
boundColumn2.HeaderText = "Application Name";
boundColumn2.UniqueName = "ApplicationName";
RadGrid1.MasterTableView.Columns.Add(boundColumn2);

//PlaceHolder1.Controls.Add(RadGrid1);

RadTab tab = new RadTab();
tab.Text = i.ToString();
tab.PageViewID = i.ToString();
myStrip.Tabs.Add(tab);
RadPageView pageView = new RadPageView();
pageView.ID = i.ToString();
RadMultiPage1.PageViews.Add(pageView);
RadMultiPage1.PageViews[i].Controls.Add(RadGrid1);

}

Hello Ramesh,

To implement the described scenario, you will need to create the grid programmatically during Page_Init:
http://www.telerik.com/help/aspnet-ajax/grid-programmatic-creation.html#Section22

And follow the steps provided in the following article:
http://www.telerik.com/help/aspnet-ajax/grid-changing-structure-dynamically.html

If you need to create column templates, here is how:
http://www.telerik.com/help/aspnet-ajax/grid-programmatic-creation.html#Section4

In case you will create an entire FormTemplate programmatically and not only Item and EditItemTemplates, you can check the attached web site sample.

Hope this helps.

Thanks - But, this seems to work for a single grid created dynamically at runtime. What about the case where there are multiple grids that need to be created during runtime. How do I get a handle to the right grid to make updates based on any edits performed by the user?

Hello Ramesh,

The instructions also apply for creating multiple or hierarchical grids:
http://www.telerik.com/help/aspnet-ajax/grid-programmatic-creation.html#Section3

Can you elaborate on your specific scenario and what exactly you have difficulties achieving?
