Filtering Rows In A Gridview?

Apr 4, 2012

I have a gridview that contains user info and one of the columns is a date when the user was added to the system. Is it possible to use the GridView.onRowCreated method to check if the user was added within a given time frame? If the user was added within that timeframe, then the row is added, if not, then that row is not added.

Note that I can't modify the datasource of the gridview, so I need to do this somehow as the gridview is being created.

Jan 19, 2011

I am working on Treeview control and Gridview Control VB.NET08. In the Treeview i have Parent and Child Nodes. Like: [Code] Comparing the Parent Node text and first two digits in the Column values. I want to add rows inbetween the gridview rows based on the parent and Child Nodes.

Rows Of A Gridview With More Than One Page?

Mar 6, 2012

Is it possible to loop through a gridview with more than one page, the gridview I'm looking at has a pageSize of 20, there are say 26 records (over two pages) and I want to be able to loop though all the records.

For Each row As GridViewRow In GridView.Rows The count of the above is only 20 as the pageSize is set to 20, I can see that the pagecount is 2 but how do you loop through the next page in a gridview? Or would I have to just iterate through the orginal datasource?

Asp.net - Dynamic GridView Has 0 Rows On RowCommand

May 14, 2009

I have a dynamically-created GridView which to which I'm attaching a handler using the AddHandler command. The problem is that when I try to refer to sender.rows within that function, it won't do anything because it says that sender.rows.count = 0. I've done enough dynamic form creation that I'm pretty sure that I'm creating the controls, binding them, and adding the handler at the proper points during the page init/load load_complete. Also, I have nearly the exact same code-behind on another form that is not dynamic, and it is able to access the values in the rows.

Considering that the RowCommand event is firing, it's clear that I'm clicking on a row. For some reason it's just not in scope for the handler event. Background: What I really want to do is access the values that are databound to the row. I'm creating a SQLCommand and binding that to the dynamic grid, and I would prefer to talk to the grid's datasource, but that doesn't seem to be possible. Perhaps I'm missing something, but for now it seems that reading the values from the GridView (which I hate doing) is the only thing that works.

Can't Get GridView's RowDataBound Update Rows After The First Row?

Oct 14, 2011

I have asked a question similar to this in the past. I was able to resolve it by removing gvRowDataBound completely from the code. This is similar code except I can't remove gvRowDataBound sub.

The issue is that when you click the Edit button of the first row, it allows you to successfully update that row.After the first row, if you click on thr edit button of any other row, enter the value to update, it doesn't update that row.

Instead, the cursor moves down to the next row. I didn't design this and having difficulty figuring out what needs to change.

How To Export Selected GridView Rows

Jan 11, 2011

I have a gridview which gets its input from a database with sql. There is a column with checkboxes in the gridview, so you can select which row you want to export. There is also a column that's called "Project Number". When you push the button "Export" the program should figure out which row is selected, get the project number from this row and connect to the database to get the data from the selected projectnumber. I already got the part where it gets the selected checkboxes. But I'm stuck at the part where it gets the projectnumber from the selected row. Must be something with Datakeys I think.

Asp.net - GridView : 2 Rows Selected And Nonexistent RowState Of 3?

Nov 4, 2010

In RowCreated of the GridView i add following script to select a row:

Select Case e.Row.RowType
Case DataControlRowType.DataRow
e.Row.Attributes("onclick") = Me.Page.ClientScript.GetPostBackClientHyperlink(Me.MainGrid, "Select$" & e.Row.RowIndex)
End Select

This works like a charm(i thought).But when i debug the SelectedIndexChanging and the following SelectedIndexChanged events, i observe that the RowState of the selected Row switches from normal{0}/alternate{1} to 3 instead of selected{2}. This occurs between SelectedIndexChanging and SelectedIndexChanged. Why does this happen? The next time i programmatically set the selectedIndex(f.e. after a new row was created), i have two rows that are selected and no (un-hacky) way to deselect the old in RowDataBound, because of the invalid RowState of 3(should only be 0,1,2,4 or 8).

how i can get the grid to select a row by clicking on any cell in the row?

The only way i can do this at the moment is by setting the AutoGenerateSelectButton property to True, but this adds a column to the grid with a crude "select" hyperlink and only selects the row if the word "Select" is cliked on.

Changing Font Colour On Alternate Rows In GridView

Aug 16, 2011

I'm looking for a way to change the font colour on alternate rows within a datagrid. e.g. normal row would be green and the alternate row would be blue. I can change either by using
me.datagrid.Styles.Row.Forcolour
me.datagrid.Styles.AlternatingRow.Forcolour

The problem is that I am having trouble using both of them together as I need to manipulate both colours. I have created a HtmlRowPrepared event and have been setting them there, however, If I set the Row.Forcolour first, it will over ride the AlternatingRow.Forcolour and vice versa. This needs to be done via SEVER SIDE code only as the colour choices are held in the database.
