Forms Data Controls :: Setting ItemTemplate Visible As True Or False While Binding Gridview?
Jun 29, 2010
I've GridView with Template field as
<asp:TemplateField HeaderText="Review">
<ItemTemplate>
<asp:ImageButton ID="imgBtnReview" ImageUrl="~/images/agt_reload.png" runat="server" Visible="false" CommandName="Review" CommandArgument='<%#Eval("id")%>' />
</ItemTemplate>
</asp:TemplateField>
Gridview is bound to a table. If a row in table has price greater than zero then the above mentioned Imagebutton should br visible in that row only.
Is it possible to do so.

I have a panel that contains several controls.
On the other hand i have a MultiView that contains Several view that in turn itself contains several controls .
In multiview we have to set ActiveViewIndex for the view which we want to see.
That same thing can be done through Panel containing another seleral panel's and setting its Visible property to True/False accordingly.
Is seems Multiview is just using this Visible property internally to render controls .Since other views (whose Index is not set to be active Index) are processed on the server for its Whole life cycle(I am confused here..whether i am right or not) .Same thing perhaps happen when we use a Panel insteed and use Visible=True/False. So, what is the difference between MultiView and Panel taking this scenario ?

In my database I have boolean column to declare if something is 'active'. In my web application I would only like one item to be able to have the 'active' status at once.
Therefore I have a radio button list in my aspx page to force the user to select one item. I know it is easy to set the selected item to true through my SQL update statement, but how do I automatically set everything else back to false/null!?

Hi I have a situation where I want to set the initial visible property of an Image to False and then in my code change it to True and then run a sub routine. My problem is that no matter how I order the code the sub runs before the image becomes visible. When I debug the image only becomes visible when it hits End Sub. Is there any way around this? Here's my code:

<asp:ButtonField Text="Void" ButtonType="Link" CommandName="Void" />
' RowCommand
Dim f_iIndex As Integer = Convert.ToInt32(e.CommandArgument)
Dim f_oSelectedRow As GridViewRow = grdMeterCorrection.Rows(f_iIndex)
Dim f_oCertIdCell As TableCell = f_oSelectedRow.Cells(11)
Dim f_sCertId As String = f_oCertIdCell.Text.Trim
If e.CommandName.ToLower = "void" Then
Dim f_bVoidRet As Boolean = VoidCert(f_sCertId)
End If
The problem is the CertId field in the GridView has visible set to false. I think this makes the value unaccessable to the RowCommand.

I have a gridview that serves as a confirmation for user input in a previous form from a previous page. The grid is databound to a temporary table where I store the user's initial selections. The user can confirm what they had submitted, (which may be more than one row of information, up to three classes) or go back and change. When they hit the confirm button, I loop through the gridview and enter a row in a permanent database for each row in the gridview. This works great.
However, I don't want the gridview to display all of the columns that are actually in the temp database, because I'm carrying over 'usersubmitted, datesubmitted', etc, from the previous page for each class selected and this is redundant. (I do need to use all of the columns when they submit, however, to make a new row with complete information for each selected class in the permanent database) So, when I set the usersubmitted column visible false, for example, in the gridview, the dataset table adapter insert function fails with a data type mismatch error. I'm assuming becuase the column has to be visible, becuase when I make it visible again it works.
Can you loop through a gridview and call on cells in columns that are not visible?
The first page is like this:
the user fills out his info once in text boxes
name ____
address____
then selects up to three classes in dropdowns:
class one dropdown ...
class two dropdown....
for each dropdown, I insert name, address, class selected into a temp db Second page.
Gridview should display only classes selected, one row for each, and not
name address class selected
name address class selected
then when they submit, I insert
name address class selected
name address class selected
one row for each in permanant database

how to bind data in an ItemTemplate column in my Gridview.
I have created an ObjectDatasource on my page bound to my Gridview using a Dataset from my linked SQL tables (PKs, FKs,etc...).
I am showing all my USERS table data in my Gridview but there are some columns which are ID's being displayed such as MembershipID, UserTypeID. These ID's are my foreign keys to other SQL tables.
I have easily been able to go into my EditTemplate for these columns, attach a new ObjectDataSource as a Lookup table, add a new DropDownList in place of the TextBox and then set Two-way binding so that the MembershipName & UserTypeName's are displayed for editing.
However, I cannot seem to work out how to do this Binding to the other ObjectDataSources in the ItemTemplate Label. Again i can make it work witha DDL, but i don't want any selections when just displaying the data in the Grid. I simply want the name to be shown in a label, but cannot work out the binding lookup?

I have an Objectdatasource configured with Select, Insert, Update & Delete queries in a Dataset. This datasource is linked to my Gridview. I do not require all fields in the table to be displayed or updated in my grid so i have turned off the Visible property on several.
However, when i go into Edit mode and trigger the UPDATE to the database table, i get NULL values updated in the columns i set False for the Visible property.
How can i remove these columns from the GridView and the Edit mode and still have them UPDATE with their current values instead of being overwritten with NULL's?

The problem is this: I am writing a system to show helptexts on certain labels. So in the PageLoad I recursively iterate all controls and save those with a certain tag. So far so good.
On the PreRenderComplete I iterate the controls and set their text property. The strange this is that the labels in ItemTemplate don't get the new text. The PreRenderComplete fires after the DataBound event of the gridview, the label gets found perfectly, in the end it has the new text, but in the page it's still the old text.
I hope I don't need the Row_Databinding event of the gridview, since I want to put all the functionality in an extender class with as little custom work as possible.

I have an update panel which has 2 set of controls each in their own separate panels. We can select either panel by a checkbox list and they become visible. Now I am trying to set a value by javascript in the panel that becomes visible on my checkbox click but the problem is that I cant access the controls through javascript as they are not rendered on page as visibility is false.
I cant find the controls inside the page source even though they are visible on page so javascript cannot access them. Is there any way other than doing a postback and setting them visible to access them via javascript?

I have a List<string> that I want to use as a datasource for the gridview, making the column a HyperlinkField type and passing the value clicked in the column in the url. My code:
private void DoBind(GridView grid, List<string> Accounts)
{
Hyperlinkfield field = new HyperlinkField();
field.DataNavigateUrlFields = Accounts.ToArray();
field.DataNavigateUrlFormatString = _urlToRedirectFromGrid;
field.DataSource = Accounts;
grid.Columns.Add(field);
grid.AutoGenerateColumns = false;
grid.DataBind();
}
I can't get this to work. The page throws an AJAX null exception when this method is called.
