and an OnRowDataBound event handler that's tied to the databinding.
In that event handler, how do you make column 2 contain 2 objects from TheSource. For instance, in the TheSource, there is a variable for FirstName and another one for LastName. Column 2 needs to contain both the first and last name in the same cell.
i'm opening a new window and passing on to it variables in a querystring, the values are loaded into a function that is filling my dataset and then filling my Gridview. after i press the button field in my grid to delete an item, the databind doesn't show the updated grid but remains the same. i've noticed that if i navigate back and refresh i see it correctly. in FF btw no problem.
How do I make a column invisible in a gridview? I tried to use this:
dataGridView.Columns(0).Visible = False
But its getting an error "Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index". How can I do this?
I can get the file(image) to display, but it displays at a size that is too large for my use. Basically, right now, I'm pointing the ImageField to the first field in the grid that contains the url of the image. I could require the user to create a smaller image of the file but that seems a little excessive. Is there any way to control the size of the column displaying the image? Here is the html, we are using LINQ to get the data that is displayed in the grid.

I bound the gridview having some fields(ID, StudName, City) and Display Button. When I click on the Disply button I approve the student and updation will happen.
Bu what happen the column ID is not in the sequence. Sometime it displays 1,2,3,4,5,6 ... next time it will display 7,8,9,10,11.... I want a sequence for the column ID. For that I used :
<%# Container.DataItemIndex+1 %>
and it is working fine.. But again I realize that these numbers are generating at runtime and i can't refer to that student. Also I don't want to display ID column on the grid view but I want to use on runtime generated column. [ i am using RowCommand for ID column ] How it is possible?
i have made a gridview which contains three fields, two textboxes and one combo box. ComboBox fetchs data from table(SQL) and when a combox box triggers, data related to combo must be added in two boxes. i did this throw another button, but i want this to be trigger directly when it clicks.
I am using Gridview and on that data is binded conditionally.the problem is that at the time of editing whole row of the grid is in editable mode and i want only few of the columns editable. my code is as follows
How to set the GridView column fixed in width size whether there is data in the column cell or not. I try below code using "ItemStyle-Width" in the BoundField control to fix the column width but column became narrower if there is no data to display in it. Is this a no solution of ASP Gridview control ?
I'm using asp.net mvc2 and trying to send a list of json objects with hard coded values from the home controller, and receive them in index.... in the code below i'm sending 1 json object. how do i send many?
I have a gridview that on it's RowDataBound event I dynamically add Image Controls to some columns.
The problem is that I lose these images on the next PostBack.
OBS: The GridView's EnableViewState propertie is already set to true
I know about the page lifecycle, but how can I persist these images if I have to add them on the RowDataBound event?
In addittion, if I add a static TemplateColumn with an Image Control and I set it's ImageUrl propertie inside the RowDataBound event it will obviously persist between postbacks. The problem is that I don't know how many columns with images I'll have, it's defined on the datasource.
I want to display gridview column heading when mouse over to the particular column in the gridview.I am working in VisualStudio 2005 with MS.Net2.0 framework.I don't want to use ajax.
Why is there a need to explicitly call GridView.DataBind() to render the gridview. Why wouldn't it render by itself automatically like how it happens in Window Forms?
I have a blank/unbound GridView control on my form and I am binding it in the code behind like this:
GridView1.DataSource = _dataSet DataBind()
Running this code populates my GridView control with all the columns and data that _dataSet has. I want to display only some of the columns, change the column names, and rearrange some of these columns too (i want the last column from the actual sql database table to be displayed first in my GridView).
I bind the GridView to a List<T> filled with custom 'Unit' Classes. Each Unit consists of several properties to fill the usercontrol. (The user control holds a table, and some labels and textboxes).How can I achieve this? Is there a simple way to bind each usercontrol to the appropriate Unit?By the way, this is my way to mimic a "dynamic" behavior of multiple usercontrols on a page. If there's a more simple way, I would like to know how!
