Setting Grid SelectedValue

[Richard Weeks]

If I have:

var radGrid = (RadGrid)source;

 

 

var selectedValue = radGrid.SelectedValue.ToString();

 

 

(it happens to be an int)

And if I then throw that selectedValue to another grid on another page view a querystring redirect, what's the most efficient way to select the relevant grid row (supposing that row exists with the equivalent value) given that SelectedValue doesn't have a Set accessor?

Thanks,
Richard

Hello Richard,

I used following code to get the SeletedValue in code behind and used the value for creating the url query string.

C#:


string selectedValue = RadGrid1.SelectedValue.ToString();

Hi Shinu, you missed the point of the question (my fault as I just brain-dumped). I'm interested in what comes after:

"what's the most efficient way to select the relevant grid row (supposing that row exists with the equivalent value) given that SelectedValue doesn't have a Set accessor?"

I want to set the selected value based on ther previously retrieved value from SelectedValue, which I sent to the page in a querystring.

Getting it is no problem but how do I select that row based on the value, i.e. how to do:

RadGrid1.SelectedValue = queryStringValue;

Best,
Richard

Hi Richard,


In ItemDataBound event of the grid, check for the DataKeyValue and select the corresponding row.

Code behind:

protected void RadGrid1_ItemDataBound(object sender, GridItemEventArgs e)
{
    if (e.Item is GridDataItem)
    {
        GridDataItem item = (GridDataItem)e.Item;
        if (item.GetDataKeyValue("CustomerID").ToString() == queryStringValue)
        {
            item.Selected = true;
        }
    }
}

Hope this helps,
Shinu.

Hi, thanks for sticking with me :)

Your solution will work, I think.

But I realised I needed something more complicated (I have multiple parent / child grids), so I am putting the values into session variables and then checking for them in the destination page.

I haven't quite worked out what I do next but that's another story!

Wouldn't it be nice to just have a set accessor on SelectedValue?
