I need my gridview to display no records when the user first lands on the page. Right now it's showing all records by default based on a query I've defined in a Table Adapter in my dataset.
I have 2 web controls that the user employs to filter data (or view all records). They are working fine--I just need to have the gridview show nothing by default.

View 8 RepliesI am having some trouble hiding a column in my GridView. For some reason when I do the following:
[Code]....
It hides the column correctly but also leaves an empty gray column at the end of my grid which is about 5px. Ideally I don't want to remove the column but hide it, but if I do remove it is it possible to remove the binded that column represents?
<asp:TemplateField>
<ItemTemplate>
<asp:HiddenField ID="HiddenFieldTime" runat="server" Value='<%# Bind("Time") %>' Visible="False" />
</ItemTemplate>
</asp:TemplateField>
When I load the page, it shows up as a blank cell. Is there anyway to hide it completely as it looks out place?
My gridiview is mostly templated fields.
I have searched far and wide and discovered that if you hide gridview colums in the Gridview's databound event, as per the code below,then the objectdatasource binds multiple times according to the number of columns you are hiding. This is definitely the case.

I have an image button on my gridview in one column, and in the next column, I have a nested gridview. What I am looking to do, is to use my image button as a way to show and hide my nested gridview. I do not want to use JavaScript, because my page already uses a great deal of JavaScript. Therefore, I want to use code behind on the button, this is what I have done so far:
ImageButton b = (Button)sender;
GridViewRow row = (GridViewRow)b.NamingContainer;
if (row != null) {
int rowIndex = row.RowIndex;
How do I use my selected row index to call the nested gridview to be visible and not visible?
I was wondering how to hide a control(lblPrice) in a gridview(Gridview1)'s templatefield, given certain conditions? Like:

Here's the background: I have a GridView with suggested meetings. A logged in member can view the suggested meetings and click button "Show" to view all suggested occasions for every meeting. What I want to do now is to hide button "Show" for a logged in member if she/he owns the meeting (i.e. is the one who suggested it = Session["memberID"]).
My problem is this: All buttons "Show" are visible. I want to hide button "Show" in those cases where Session["memberID"] is identical to dr[0]. 'ID' in the SQL statement is the ID of the meeting in the database and meetingID are the ID's of the meetings shown in the GridView.

I have a gridview control which gets data from database. One of the column is a checkbox and based on the value of the checkbox, I need to display 2 more columns. Currently I am having 2 issues:
1. I am able to achieve this when OnDataBound event gets triggered. Basically I am checking the row state and type and if it is in Normal mode I check the status of the checkbox and based on the status I am setting the style on the columns I want to hide (columns contain checkboxes). But for some reason, I am not able to hide the header. The GridView shows the header but the text boxes which are in the columns are hidden.
2. During Edit mode, I have attached a javascript to the checkbox and when the status of the checkbox changes, it hide/unhides the columns, again header cannot be made hidden. Also, if I use the Visible property of the header, I can make the header invisibly (only using the code behind) but when javascript is invoked on the checkbox during edit mode, it cannot find the controls as they are not visible and hence does not do anything. Since TemplateField does not support style property I can't even set the style["display"].

I have a gridview with columns (pseudo-code):
<COLUMNS>
AuthorFirstname
AuthorLastName
BookTitle
YearPublished
</COLUMNS>
what I would like to do is to only show the AuthorFirstName and AuthorLastName columns for the first row of each author. I am easily doing this with:
[Code]....
However the issue that I'm seeing now is the formatting what happens is that after the first row that the Author names are hidden but then the BookTitle and YearPublished become the new cell(0) and cell(1) respectively which means that book and year are displaying underneath the author names columns. so my goal is to do 2 things:
1 have BookTitle and YearPublished render under the correct headers and
2. For the second row and after I would like the cell to appear the same as the background, I dont want the user to be seeing what looks like an empty cell or textbox there.
I have been trying to hide a column but make use of the value in another function but the function i am trying to hide it give me and error at the embolded line. System.ArgumentOutOfRangeException: Index was out of range. Must be non-negative and less than the size of the collection.

Working on a site where a user does a search, it takes the input from the user and then runs an SQL command to return the data in a gridview for the user to see. I also have a button where the user can see all the results from the DB (this will be taken out later but for now the DB is pretty small) This is all working fine, but the problem I am having is that when you look at the page source the gridview populates everything in tables on the page. This makes it really easy to just copy and paste and get everything from my database. How can I go about displaying the information to the user in a gridview, but hiding the table information in the html page source?

I have an SSRS remote report whose URL I want to give to intranet users. But the report is displayed in report manager in internet explorer, users can see the Home, My Subscriptions | Site Settings | Help links at the top of the report. So if a user clicks on the Home link, they might get access to the other reports they are not supposed to. Is there a way of formatting the url such that those links that appear above the report in report manager are hidden by default when the report is vied from the that formatted link?

View 5 RepliesWhen a Gridview row is in edit, I need to default an empty textbox to today's date. I am close, but the defaulted date is is not saved to the database. I can key in the date and the date is displayed and saved to the database. Even more interesting:
1. The date is defaulted to - 5/17/2010
2. If I erase the month and key the "5" back in the data is not saved.
3. If I erase the month and then change the month to "6", the data is saved to the database. If any value is changed in the date the save works.

I am working with Asp.net 2.0, C# and Sqlserver 2005. I have a web page with gridview and Button. On button click, I should be able to export the gridview to a excel file and open that file as an attachment to a user's default mail client. I tried with the below options but didnot succeed.
1. mailto : I tried with this option but not able to open the mail client with attachment.
2. Outlook interop : Using Outlook COM reference, I can able to open excel file as on attachment to default mail client, but this is working fine on local system but not on the production server. I am not sure whether I can implement this kind of functionality using web application as some people say this is a security issue.

I have a gridview which displays thumbnails in the first column and details in the other columns. The thumbnail URL is being retrieved using the following:
[Code]....
However, if the thumbnail cannot be located, a white box with a cross appears instead (as expected).
To handle this better, I would like to display a different image if the thumbnail cannot be located for any reason, for example an image saying "Image Cannot Be Displayed". But I am unsure of how to do this, of even where to do this. Essentially I need to assess the value that the datagrid is using for the particular URL when it is databound. But can I put VB.NET code in this?
