Forms Data Controls :: Can Write But Not Read CssClass Of A GridView Cell
Feb 24, 2010
I have a GridView where some of the BoundFields have a CssClass applied:
<asp:BoundField ... ItemStyle-CssClass="foobar">
In the rendered HTML it looks like <td class="foobar">
But when I try to read the CssClass programatically in an event like RowCreated or CheckboxChanged or PageLoad it returns nothing:
For Each row As GridViewRow In gv.Rows()
For Each cell As TableCell In row.Cells()
ltlMsg.Text += cell.CssClass
Next
Next
(gv is my GridView and ltlMsg is just a Literal for displaying the results)
If I replace cell.CssClass with cell.Text it does display results, so the code is running.
If I change it to cell.CssClass="test" it does set the class of the <td> elements. It just can't seem to read them.
I must have missed something obvious - I've tried putting it in various different events but nothing seems to work. I assume the CssClass must get set at a later point in the event cycle than I have tried. Can anyone recommend a link to documentation that shows the order in which all the events fire?
Eventually I want to use this to show or hide certain columns in the GridView based on whether a CheckBox (outside the GridView) is checked or not.
Here is the setup: I programmatically populate my gridview using LINQ to SQL query. Then I enter the edit mode and want to replace some standard TextBox controls with DropDownLists like this:
[Code]....
At this moment I have my gridview showing standard textbox control and new DDList control (in the Column 1). The problem is -- I cant read the value from DDList in the RowUpdating method. It seems like DDList control is not in the GridView1.Rows.Item(0).Cells(1).Controls collection. RowUpdating method sees only standard TextBox control and can read it's value.
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)
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 write css like above for datalist label. but it is not working. which way i have to write cssclass to binding datalist. as i notice you have use css class at jquery to set value like below.

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; }
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.
It does not give me any errors and seems to work but the grid view cell do not take this session. When I'm clicking on the edit hyperlink this event is triggered.
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 have a gridview with a bound column,a template field with an editable textbox and a template field with a readonly textbox.
The bound field value is coming from database. I will enter a value to the editable textbox field. I want to set a value to the third cell based on the entered value in second cell . If the second cell is lost focus i want to set the value to third cell . If the solution is with a javascript function i will be very happy.
