I'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:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click
I have a grid view populated with some data included bit fields and I made an export to excel function For each row i need to check the cell with the bit value to change the cell color, but the cell is always empty, even if is the field is set to False or True. foreach (GridViewRow row in gv.Rows)
View 2 RepliesI have a gridview and I want to update a cell with a session variable username. In the Gridview1_RowEditing event I have this code :
GridView1.Rows(e.NewEditIndex).Cells(5).Text = Session("username")

I have a situation where i need to update my Dropdownlist templatefield inside a GridView....but only for a specific cell. I have seen codes like this to loop through the whole GridView and update every rows in a specific column, but how do i do it if i only want to update one specific cell ? (If i know the index information of the cell, for example, I know i want to update the dropdownlist on Column 3 and Row 2)
foreach (GridViewRow row in GridView1.Rows)
{
if (row.RowType == DataControlRowType.DataRow)
{
this.WorkTypeDDL = ((DropDownList)row.FindControl("WorkTypeList"));
this.WorkTypeDDL.DataSource = AL;
this.WorkTypeDDL.DataBind();
//more codes blah blah blah//
}
}
I have an asp.net page with a gridview control on it but I want to allow the user to also be able to update the selected row from a series of textboxes. I simply need the code for a button click event to do this.
button is called button1
textbox is called textbox1
gridview control is named gridview1
record to be modified is in 3rd column called PlayerName
The row to be edited will always be the only record shown and will always be selected by code I've already written. I will also need to know if the record must be set to edit mode to make the button click code work.
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.

What i need is a simple way to set a specific gridview cell with my passed JS variable.
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)

I am using this command to trim a cell value from a grid view.
row.Cells[i].Text.Trim().Length
The result return is always 6.
I have checked that the value of this is empty, when I display it on page using this code,
