Forms Data Controls :: How To Set Selected Value Of Dropdown In Gridview After Gridview Databound

Nov 30, 2010

I have a gridview with dropdown boxes. As soon as the complete gridview is databound, I want to loop through ALL the rows and set the values of the dropdown boxe in a row based on the value of another column in the same row. The gridview is databound, all data shows up. The condition "If ddl.Items(j).Value = searchstring Then" evaluates as true, but somehow the selected item in the dropdownbox is NOT changed and remains "<ignore>"

Forms Data Controls :: GridView - Selected Row?

Mar 23, 2011

I have to GridViews, say grd1 and grd2.

grd1 is bound programmaticaly in Page_Load, it contains hyperlink column that loads the same page with ID value in request.

grd2 also is bound in Page_Load and it depands on ID from request (so, after grd1 is clicked grd2 loads data).So, actually grd2 depands on grd1.

After page is reloaded with id in request, I should know the row from grd1 where user has clicked and display some of column data seperatly (say in label lblColumnData). How to know which row was clicked?

Forms Data Controls :: Getting Row Selected From GridView?

Jan 1, 2011

I have a gridview that uses a dynamic dataview as the datasource. Only some of the items in the dataview are included in the columns of the grid.

Dataview: Name, Address, Phone Number

GridView: Name, Address

When a user selects a row, I want to access the datafield not shown on the grid. Here is how I chose to do it.

[Code]....

Everything works fine with every row I select. The problem comes when I add the following code:[Code]....

I get the error:

Index was out of range. Must be non-negative and less than the size of the collection.Parameter name: index

This error occurs at the first part of the code where it is referring to the selected index. How can the second part of the code cause an error in the first part of the code that was working perfectly?

Forms Data Controls :: Get Selected Row Cell Value In GridView

Feb 1, 2011

Objective : Get the value of a particular cell in a particular row - when I click on a template field button link. How do I "select" that row so I can use code like datagridview.rowselected

or datagridview.selectedrowindex etc...

Right now I am using code like that and it does not get any values of the gridview because it does not know what the selected row is (may be because I want this to be done on template field click)

Forms Data Controls :: Checkbox In Gridview Not Selected?

Nov 3, 2010

I have designed a gridview with a radio button inside the itemtemplet. I also have a confirm button. A user is allowed to check several radio button and when a confirm button is pressed then database is updated with the value of radio button.

But when i check the button it is shown as checked in UI but when I check through code behind, it shows checked property of radio button as false.

for (int i = 0; i < gvTransaction.Rows.Count; i++)
{
if (!((String.IsNullOrEmpty(gvTransaction.Rows[i].Cells[0].Text)) || (gvTransaction.Rows[i].Cells[0].Text == " ")))
{
string transactionID = gvTransaction.Rows[i].Cells[0].Text;
RadioButton btn = (RadioButton)gvTransaction.Rows[i].FindControl("rbtSelect");
if (btn.Checked)
{
Although the radiobutton is checked code never reach here.
}
}
}
