I am using VB and trying to get the first value of the cell of a gridview. The gridview is returning a header and 1 value.
In the code behind I have used the below, but the textbox is showing " ". It is not populating the first cell of the gridview databind.
Protected
Sub GridView3_RowDataBound(ByVal
sender As
Object,
ByVal e
As
GridViewRowEventArgs)If
(Not (e.Row.DataItem)
Is
Nothing)
Then
' Set the capacity label text
TextBoxTest.Text = e.Row.Cells(1).Text
End
If
End

i am having trouble to set a new value to a specific GridView cell.
The value is passed from a javascript to the c# code behind where it should update a specific Gridview cell []:
I am not using editedtemplate.
code c# :
[code]....
In other hand I am using a JS code that set a GridView cell value.. The new value is set but as soon as i select another row on the GridView ..the Updated cell comes back to its original.
JS code1 :
setCellValue(selectedIndex,5);
JS code2 :
[code]....
What i need is a simple way to set a specific gridview cell with my passed JS variable.
I have been looking to see if there is a simple method that would allow me to get the contents of a cell when I mouseover it. The purpose would be to use the data (in this case CustomerId) to display more detailed about the contents (in this case First Name + LastName).I am looking for something like this - but instead of changing the cell or row colour gives me the cell content so that I can create a popup

I have a gridview which i bind to DataView. I need to manipulate text on cell[2] of each row. I was wondering if i could do it in the OnRowCreated event? cell[0] in asp looks like this
<asp:ButtonField DataTextField = "header" CommandName="select" HeaderText="Overskrift"/>
This doesnt work. test = null
protected void onrowcreated(object sender, GridViewRowEventArgs e)
{
TableCellCollection cells = e.Row.Cells;
string test = cells[2].Text;
}
Is it possible to show a GridView cell's content using AnimationExtender control in AJAX control toolkit?

i am still stumped with this operation: i am trying to retrieve a GridView selected row data..here is my code.. the commented part that gives me the selectedindex works just fine....but the one giving the selected row cell value does't work and there is no error.. The update operation is done successfully...weired. i need to assigned selected row cells values to variables ..do some calculations and then re-assign the result calculation to cell[9]..
protected void GridView1_RowUpdating(object sender, GridViewUpdateEventArgs e)
{
string s = GridView1.SelectedRow.Cells[5].Text;
TextBox1.Text = s.ToString();
//string s2 = GridView1.SelectedIndex.ToString();
//TextBox1.Text = s2.ToString();
}

View 2 RepliesI'm having a weird problem where the GridView cell that I'm programmatically updating turns grey, and throws a null error when attempting to save row. I have been searching all day and have not been able to find a solution. I'm guessing there is a problem with my code, so here it is:

I have a datagrid whose columns are autogenerated (based on the results from an SQL SELECT query). However, I need to retrieve values from certain cells across the datagrid, using the following code to step through the results.

I need to specify all my columns using TemplateField?
I am trying to update the database with the edited data. However, it did not manage to read the edited data from the textbox. It returned the retrieve data that I have done in the Page_Load instead. Is there any part of the code that I have written wrongly? I did manage not to use <EditItemTemplate> in my past project and manage to update the database with the same logic.

How to set Height and ItemSource(Business Object as DataSource for Cell) for every Cell in DataGrid/ Grid? Shown below is part of code I am currently using with Grid Control. What I am currently doing is that I am using ListBoxItem, set Item Height and ItemSource at ListBoxItem Level, Add ListBoxitem to ListBox and then Add ListBox to Grid, It leaves me with just one row and multiple columns in the Grid, which is perhaps not the best way of doing it as it doesn't allow me to take benefits from UI Virtualization of Grid.
[code]....
I am open to use any control i.e. Grid/ DataGrid provided it allows me to set Cell Height and item source at Cell level. In my requirement, Cell height depends on the Item duration and size of image, which means the height of the cells may not be same across cells in any particular row.
I am using this command to get the value of a particular cell in the GridView: Question: Do you know why I do not get a value in strValue ?
There is definitely value in the grid.
protected void grid_RowCommand(object sender, GridViewCommandEventArgs e)
{
//proceed only if the Details button is clicked...
if (e.CommandName.ToLower() == "details")
{
//Get the row index selected...
int index = Convert.ToInt32(e.CommandArgument);
GridViewRow row = grid.Rows[index];
string strValue = grid.Rows[index].Cells[1].Text;
}
