Hello Hsakarp,
You can get the text from the WHDG Child Column using the following code.
protected void WebHierarchicalDataGrid1_RowIslandDataBound(object sender, RowIslandEventArgs e) { ContainerGrid childGrid = this.WebHierarchicalDataGrid1.GridView.Rows[0].RowIslands[0];
string str= childGrid.Rows[0].Items[1].Text;
}
Please let me know if you have any further questions regarding this matter.
Hi Prabha,
When i tried the code am getting the exception :"Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index".When i checked the IsrowIslands property it is showing as true.Even i tried with index value from 0 to 2.Please respond to this asap.
Hsakarp.
In which event are you trying to access the value?
I suggest you to handler rowislandbound event.
I am trying to get the value from the template field in the child grid.am having a textbox in the third column of the child grid am trying to get the value from the textbox.I have tried with findcontrol property but it return as null.
I found that.
ContainerGrid childGrid = this.WebHierarchicalDataGrid2.GridView.Rows[0].RowIslands[0];
Textbox tb = (childGrid.Rows[0].items[2].FindControl("id") as TextBox);
string value = tb.text;

It is giving me the error as "Index was out of range. Must be non-negative and less than the size of the collection."
Please let me know if I can provide any further assistance regarding this matter.
