View 3 RepliesI m getting 9 columns from database in a dataset but I want to diplay only 4 columns in datagrid. Remaining 5 columns values, I want to display in the textboxes below datagird.
I tried it making column invisible. If I make it invisible, I m not getting any value for that column to display in the textbox.
I bound the gridview having some fields(ID, StudName, City) Â and Display Button. When I click on the Disply button I approve the student and updation will happen.Â
Bu what happen the column ID is not in the sequence. Sometime it displays 1,2,3,4,5,6 ... Â next time it will display 7,8,9,10,11.... I want a sequence for the column ID. For that I used :Â
<%# 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?Â

How do I make a column invisible in a gridview? I tried to use this:

regarding gridview Template column.in my template column i have a textbox and i need to invisible to user. but when i set visible property "false" then textbox value is not render.

i need to set the column width of my gridview.
However the the column in the gridview is dynamic created which might more or less depend on system logic.
I have try to set the column width in row_created event, rowDataBound event, but it show me that no column is available by using gridview.columns.count.
I have an ASP.NET/C# web application that has a GridView control. In the last column of that GridView control I have a template field that contains a menu. In the OnMenuItemClick event I get a reference to which row the event was fired from, in order to determine what value the ID field contains for the current row. Currently I reference this cell by it's index "gvr.Cells[1].Text". However, this is highly volatile since any changes to the location of the ID column breaks the code. How can I instead gain the value in the cell that has a column name (or some other name-like property) of "SomeID" from a GridViewRow reference?
View 6 RepliesI have a ASP.NET/C# web application that contains user controls with GridView controls. The GridView controls contain the following column types.
CommandField - Contains buttons like Edit, Select, Delete, ...
BoundField (x8) - Contains the data fields from the database.
TemplateField - Contains a single ASP:Menu control.
The menu control consists of the following structure.
Navigate To (Parent MenuItem)
- Location A (Child MenuItems)
- Location B
- Location C
- Location D
- Location E
What I need to do is when the OnMenuItemClick event is fired, determine which menu item was clicked (already done) and then capture what the value in the first BoundField cell is for the row that the menu item was clicked on.
So, for instance if I have three rows in the grid with the first BoundField column containing the IDs 1, 2 & 3. Then I hover my mouse over the menu on the 2nd row, and click the menu item "Location C". The "Menu1_OnMenuItemClick" event is fired and I can determine that "Location C" was clicked by e.Item.Value == "Location C".
However, how do I navigate up through the API to determine what the contents of the cell in the first bound field column are for the row that was clicked on?
provide an example to do that... "Hide column if row is empty" in Databound()
datasource could be .1
coulmn: id-value1-value2-value3
row: 1-4-3-NULL (output: hides row value3) because the value is NULL
.2
coulmn: id-value1-value2-value3
row: 1-4-NULL-NULL (output: hides row value2,value3)

View 2 RepliesI 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 have an ASP.NET GridView control in a Web Form. For the sake of simplicity, I will say that this GridView is defined as follows:
[code]...
When each of these rows is bound (a.k.a. during the "myGridView_RowBound" event), I want to get the ID, Name, and Age values. My problem is, I cannot figure out how to get the "ID" value. The reason why is because it is in an invisible field.
