In Gridview as follows
coursename coursedate coursecode
RAFF 30 mar 14 PSTF
RPST 30 mar 14 PSTF

I want to compare the Gridview 3rd row coursecode(AMC) and Repeater control 2nd row coursecode(PSTF). if both course code matches i want to show the message coursecode matches.if both course code not matches i want to show the message coursecode not matches. For that how can i do in asp.net using c#.
i have a gridview with check box in it and I also have a button separately.The gridview contains students name and their school name.User will select rows in gridview with the check box and click the button.Now what I want is, if user select students from two different school, system will display message ("wrong selection").But if user select student with in the same school, system will work as it should be.so, how can I compare the rows??
have a page that has a results gridview where I have all rows with a chekbox. when I click on the checkbox I try to create an excel filethis is method content:
DataTable MyData = new DataTable(); //recorrido sobre los elementos seleccionados6 foreach (GridViewRow row in gvwDbf.Rows)
[code]...
The problem is that excel file is totally empty. When I trace on the error I find that (item on bold above) dt datable has current record as I expected but Mydata table has nothing inside. shouldn't I use import statement? How can I get the row copied? I intend to have a full table made by every record coming from parameters of each query which is performed inside a for each sentence
I am using C# ASP .NET 2.0. I have a web form with two DropDownList controls. In my code behind I get data from a DataSet. One column is a string (Month), and another is an integer (StatusID). I am setting the selected item in the each DDL in the code behind by doing this:
[Code]....
I have a button with a Click event. What I want to do in the click event is be able to check if the currently selected item in each DDL (if the end-user changed the selection) is different from what was selected in the above code.
I have nested a repeater control in Gridview. Right now it is showing gridview rows and repeater header for every case(whether data is there or not for that particular grid view row in the repeater control). I want to hide the gridview row and repeater control header when there is no data present for that particular gridview row. That case I handled at code level by filtering the resulted data table.
Now the another problem I am facing: I have allowed the paging on the gridview i.e. pagesize 3. When page loads it works fine, but when I go to page 2 then it generates following error: Index was out of range. Must be non-negative and less than the size of the collection. Parameter name: index
Below is the code to fill the grid, paging and fill repeater on rowdatabound event of grid.
I have an xml repeater deployed on two different pages. On the "News" page, I'd like to show all the items (which works fine), but on the "Home" page I'd only like to display the three most recent items.The code I'm using is below.
I've read that you should write repeaterControl.DataSource = null to clear the items in the control, but it doesn't work. Does anyone have any tips or links to articles about this problem?
When attempting to place controls in different content areas using Masterpages and trying to use a compare validator, I get the error: Unable to find control id 'txtStartDate' referenced by the 'ControlToCompare' property of 'cvlDate'. I have also attempted to set it within the c# code behind in page load: cvlDate.ControlToCompare = txtStartDate.ID and by using findControl there must be an easy way to achieve this?
Here is the situation I have, I have a repeater inside a Usercontrol. The datasource is a IEnumerable<Investor> Exposed through a UserControl's Property. I have overridden the UserControl's databind event to set the Repeater Datasource before databinding the repeater. When it's not a postback, it databinds find and the events on the repeater item's controls fires up fine. But there is one event on repeater items (Delete Investor) which call back the DataBind of the UserControl after removing the Investor from de datasource. When this Event is called, it does all the work (deleting the investor and so on...) calls back the usercontrol's databind but when (within the usercontrol databind) the repeater is databinded again, the repeater items doesn't update (repeater items for investor not on the DataSource anymore still appears). My ItemDataBind doesn't even fire by then.

I Tried with both the Repeater Item Command and each LinkButton Event to see if it would make any difference, but none worked
I am currently in the process of writing a facebook type 'activity feed' for a site. Currently I am binding the last 10 items to a repeater control, which contains a usercontrol representing each item. The requirement is that when a user clicks a refresh button any new events are added to the top of the list, the previous items drop down and the equivalent number of old items drop off the bottom, all with nice slider transitions. I have put the repeater inside of an update control and are able to handle the transitions by using RegisterStartup script to drop jquery calls onto the page for the slider. However I cannot find a way to dynamically add or remove new datarows to the repeater.
I need the old items to stay in the repeater and be pushed down by the new items, so completely refreshing the datasource seems like a bad idea.I was thinking about maybe storing the datasource in the viewstate and adding rows to that, maybe with an extra column on the end which stores what transition is needed on the databind for my jquery, but there will be a 'View more items' link at the bottom of the page, so I am worried that the list could get pretty large and there would be a big problem with memory.
And I am binding these repeater control with some datasource.
My requirement is to have focus on first item row and i should be able to use tab ket to navigate between various rows of the repeater control(which is ultimately a table)
There is no anchor(<a>) control inside the table.
I am using onclick event on table row which does something in my application.
I want my user to use TAB key to navigate between rows.
I'm looking for the correct syntax to get me the last row of a repeater item and use it in a literal below. As you can see I have the item index syntax already. assume that there is a repeater control surrounding the literal already.
I have already bound the data so it will not use obitemdatabound .
<asp:Literal id="Rpt_ItemCount" runat="server" Text = '<%# (int) DataBinder.Eval(Container, ItemIndex"))%>'></asp:Literal>
Using C#, how can I check the total number of rows returned from a database when using a Repeater? The reason I need to check is I need to alter the presentation of the data when there is only 1 row returned.
