[Solved] How to return value from RadAjaxManager1_AjaxRequest ?

[Virendra]

Hi,

I have a radGrid, 

in RadGrid1_ItemDataBound, i am attaching clientside event  

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)

{

if (e.Item is GridDataItem && e.Item.IsInEditMode)

{

GridDataItem item = (GridDataItem)e.Item;

TextBox textBox = item["CompanyName"].Controls[0] as TextBox;    // Get the textbox for column CompanyName      

textBox.Attributes.Add("onFocusout", "OnRadGridCellFocusOut("+ parameters +")");

}

This client event makes an AjaxRequest when the column loose focues

function OnRadGridCellFocusOut(RowIndex, ColumnIndex)

{

$find("<%= RadAjaxManager1.ClientID %>").ajaxRequest(RowIndex + ":" + ColumnIndex);

}

In AjaxRequest Handler

protected void RadAjaxManager1_AjaxRequest(object sender, Telerik.Web.UI.AjaxRequestEventArgs e)

{

//do some processing to update the next column

}

after the processing, i want to update the value of next column.

for example

if Col1 is updated to IBM i will make Col2 as 'Partener'.

i was thinking if AjaxRequest can return a value to clientside caller, i could update it from there.

What is the best way to do it?

thanks

Hello Virendra,

A suggestion is to directly pass the client ids' of the textboxes from server to client side and then perform all the operations at the client itself rather than performing several round trips. Try out the following code and see if helps meet your requirement:
c#:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
    {
        if (e.Item is GridEditableItem && e.Item.IsInEditMode)
        {
            GridEditableItem editItem = (GridEditableItem)e.Item;

            TextBox textBox1 = editItem["CompanyName"].Controls[0] as TextBox;
            TextBox textBox2 = editItem["Col2UniqueName"].Controls[0] as TextBox;
            textBox1.Attributes.Add("onFocusout", "OnRadGridCellFocusOut('" + textBox1.ClientID + "','" + textBox2.ClientID + "')");
        }
   }

js:

 function OnRadGridCellFocusOut(textbox1,textbox2)
    {
       var text1 = document.getElementById(textbox1);
       var text2 = document.getElementById(textbox2);
       if(text1.value == "IBM")
           text2.value = "Partner"

    }
