I have a gridview, which has a hidden column, and I am using this column with the value contained within as a flag. What I would like to do is to use this hidden column with a LinkButton that will execute some JavaScript.
Can someone show me, or point me in a direction of an example, which goes through the rows of a gridview and can show or hide rows in a gridview based upon a value?
On a page of my project, i have a gridview, i need to perform following operations with it:
1. On Page_Load i want to bind all the data (100 Rows) with the gridview.
2. On my Page i want to show only 4 records with Show More/Show Less Links.
3. When user clicks on the link, i want to show All data or 4 Rows accoeding to the link.
4. I don't want any roundTrip to the server, so plz don't suggest AJAX, i want to attain this by using Javascript.
I have developed a gridview that groups rows together based upon a field in the gridview. To separate each group, I have inserted a row that contains the name of the group.
However, I have hit a problem, what I need to do is to have an image button on the row I have inserted between the groups, which when clicked will hide and show the rows in that group in a toggle fashion. I can get the start of the row for a group, but I am unable to work the number of rows in a group and to then show and hide the rows in that group.
I am looking at building a grouping gridview, which I will know, will suit my needs. Therefore, I am not looking for a nested gridview. My answer is based upon an example I found at [URL]
However, what I am looking to do is to add a button to the group header row, which when pressed the rows within the group can either be shown or hidden.
On Row databound i want to show some rows in If and Hide in some rows in else conditon. But it generate an exception that (Index was out of range. Must be non-negative and less than the size of the collection Parameter name: index.
protected void gvHotels_RowDataBound(object sender, GridViewRowEventArgs e)
{
DataTable dt = new DataTable();
if (e.Row.RowType == DataControlRowType.DataRow)

I have a webpage that lists information about trucks and their map sections and whether the combination is active and will be used.
On the page I put a check box that says Show Only Active and marked the checked property as true by default. When the RowDataBound event fires I check to see if that checkbox is marked as true and if it is I check if the individual map sections are marked as active. If they are not active then I set the row visibility equal to false like below.

I have a gridview, which contains a template field with a button. On this button, I want to show and hide another column with this one button. I don't want to use Java Script because my site already uses a lot of this and AJAX. So, can someone show an example of some code behind, which is what I want to do on how to show and hide another column on a gridview?

I've got a grid view on my form that is bound to a data table at run tim. The data table is returned by a function rather than direct from the DB so I can't set the datasource at runtime.
I bind the grid in the page_load event like this:-
Code:
Dim _dt As System.Data.DataTable
_dt = _srvc.GetVinylShutters(0)
_dt.Rows.Add(_dt.NewRow)
grdShutters.DataSource = _dt
grdShutters.DataBind()
(_dt.Rows.Add(_dt.NewRow) is just there to add a blank row in, otherwise I wasn't seeing any columns at all)
I've then got the following snippet which I want to use to hide some underlying columns:-
Code:
For Each col As DataControlField In grdShutters.Columns
Select Case col.HeaderText
Case "OrderID", _
"ShutterID", _
"ModelID", _
[Code] ...
The thing is, wherever I put this it doesn't seem to hide the columns. If I break into the code I can see that grdShutters.Columns.Count equals zero althought I can see that the bound datatable has 38 columns.
I've tried the Page's Load, LoadComplete and PreRenderComplete events as well as the gridview's DataBound, RowDataBound and RowCreated events. I get teh same result in all of them. The grid doesn't actually have any columns until it appears on the screen.
I have a datalist bound to a sql source having two columns: Name and Description. The datalist contains a "Show Description" link as follows on clicking on which it calls the javascript which shows the description div.
[Code]....
The asp.net page source for itemtemplate of the datalist is as follows.The problem is that since the div id "Description" is applicable to multiple records, no matter I click on whichever "show details" link, the description of first record in the datalist is shwon and hidden since its the first div encountred by the javascript. In other words, I want a way to show/hide the description of each record in datalist indivigdually.

View 4 RepliesI have a set of dataset with different column retrieved from DB. I need to present the datasets in one GridView (or other ListView etc...) without specifying the column_header. It should present automaticly since the GridView is bind to the DataSet.
In additional, I want this GridView to handle multiple rows edit and update the dataset, idealy, show data in textboxs in initially.How could I set the GridView to edit_model without hardcode column_header and textboxs in 'itemtemplate' or filed.
How could I achieve the bulk edit and update, so that I can assign 'mydataview1.table' to the dataset.
