Hide Gridview column based on the column value
I have a grid which i bind with values from Database. I have events to edit and update the grid. I am not using SqlDatasource to connect to DB. Rather i am doing the updating of the grid Programmatically.
The Grid is populated based on a dropdown selection
Gridview has 4 columns, LID(item template column) ,LVal (Item Template and an Edit Item template column), Lookupid (Item Template and an Edit Item template column) and "Edit" link
4 of 10 Dropdown selections have values in Column 3 (lookupid), rest dont. When they dont have values i want to hide that column 3. Of course i can ...Hide a Gridview column but use the value in that column when the row is selected.
I need to retrieve a column from my database but do not want to display it in the gridview. However, I need to be able to show that information later in the application. I am using the wizard control. I believe I can use the DataKeyValues property of the gridview but can't figure out how to write the code to get the value of the cell in that column when the row is selected so it can be referenced later. I am using VB. Thanks for your help!!
Found the answer. Here it is in case anyone else needs it:

Hi allI've come across a unusual problem that I can't work out. I'm using VB by the way. I have a gridview that is populated from a "suggestions" database and contains 6 databound columns - ID, Firstname, Surname, Department, Suggestion, HideName. The gridview pulls the details from the database and displays all the values as should be. When a user adds data to the databse they have a option to hide their identity by placing a tick in a checkbox. This all gets updated without any issues. The Firstname and Username get automatically populated from their User ...Change Another Column Value based on Dropdownlist selected value while gridview onrowediting
Another gridview question again.
I have a gridview, with three columns, Code, Description and Action.
The Code column, when I click on the Edit linkbutton on the Action column becomes a dropdown list.
How can I do that when I selected a value from the dropdownlist, the value of the description on would be changed to the description corresponding to the dropdownlist?
From your description I think you can try:
1. Set AutoPostBack=true for your DropDownList.
2. protected void DropDownList1_SelectedIndexChanged(object sender, EventArgs e) &n...Insert multiple values(multiple columns) based on single dropdown list selection.
What I would like to accomplish:
I have a dropdown list that is an entityref(populated by values from PK in separate table).
When user makes selection in dropdown list, then clicks “Insert”, I would like the selected value to be inserted into the applicable FK column, but also would like to have a value equal to the integer selected, multiplied by 50, inserted into another column of the same table.
Example with user selecting “2” in the dropdown list, inserting into Table b:table a: Column: Numbers(PK)
(1, 2, 4, 8)
Table b: Processors(FK)
Inserted: “2”Table b: Factor
Inserted: ...how to hide gridview columns based on CheckBoxList selections?

I'm using C#
I have a gridview with a checkbox in the first column along with a button in the last column. Based on a rows value (on load), I want to make the checkbox grey or not clickable and then enable the button in the last column for that row. If the value is different I want the checkbox clickable, but I want to hide or disable (make it grey) the button in the last column.
I'm using the RowDataBound method and have access to the row as it loads. But do not know how to change the checkbox to grey or disabled (same for the button).

I would like to show/hide columns of my GridView based on user events.
When the user clicks on a specific button, I would like to show/hide certain columns based on the column's name. I can't seem to get this working. When I do GridViewName.Columns, it only allows me to use an index and not a string to find the column.I can easily show/hide the columns based on the index of the column, but I would rather not hardcode index values in my application. If I were to add or remove a column at a later date, I would have to go back through the code to adjust the indexes.

I read the article, sounded interesting although I've done it several times in asp.net (vb), not in C# as this article is.
I wonder what the author tries to prove with this article since you cannot run it and see what it does?
Since there's some hints that it might be using the Northend database there's no sign of it in the code, thus you can't do anything. Has the author deliberatly left out the datasource so that noone will ever know what the code does?
Or is it so that he never thoght of the datasource since that worked in his machine, and he thought if it does work on hi...
