I've implemented a ListView to display selected data from a DataTable. My listview is one row high and 4 columns wide. I've setup a DataPager to the left of it and another to the right to allow the user to access any item in the ListView.My problem is simple: When the user adds a new item to the DataTable, I rebind the data again { e.g. listView1.DataBind() }, and then I proceed to select that newly added item. BUT no matter what I try, nothing works! More precisely, I do this: listView1.SelectedIndex = #; where "#" is the appropriate index number.

When "btnEdit" is clicked, "RowCommand" event is raised where I want to the catch row index of the row which was set to Edit mode.The Reason for doing this is ......I am using paging with page size = 4. When I click the fourth row (suppose), page is postedback and then the user has to scrolldown to get to the edit row
I have a GridView with drop down boxes that are always in edit mode, and what I want to do is when the user sets a value in one of the drop downs I want to set the value in all of the drop downs BELOW that one (if they are not currently set) to the same value. However, the RowEditing and RowUpdating events never fire because techncially I'm not editing or updating the row.
Here is what I'm wanting to do, something along these lines:

how to loop check index in repeater control ?
View 1 RepliesI have created an application in asp.net 4.0 and entity framework4 . I have also implemented the routing feature introduced with this version of asp.net.I have page which displays a list of products and the paging is taken care of using datapager control.Now, when the user selects a particular product (using the checkbox provided besides it), I show the selected product's name on top. As the user goes on selected products the product_names are added on top. This functinality I want to achieve using javascript. When the user switches between different pages to select a product the already selected product names should be retained between different pages. I want to implement this whole fuctionality using javascript.My problem is how do I retrieve the page index from the datapager so that I can retain the selected values.Is there any other better way of doing it. I had already faced numerous problems in using javascript because of the routing functioanlity. But still I first want to see if there is a solution using javascript.

View 5 RepliesI have a simple grid with 5 columns. The first 4 are numeric values I have formatted with templates. The last column is a total and I've added the Update button on the end. When the Update button is pressed, I have it updating the table with the new values and calculating the Total column. My goal is to have the Total column calculated after each cell is updated and not when the Update button is pressed.
I've added CommandName="myUpdateRowTotal" to
my templates.

Right now I have a gridview with databind. My menu item consist of the 7 days of the week. Everything works fine except for one thing, the page index. Right now by default it loads the results for Monday. If I click on Pg 2 for Monday, and then I click on Tuesday, the page number stays at page 2 and the data remains the same. I have to click on Pg 1 or Pg 3 before the data would refresh and change the result to Tuesday's data.
I've tried adding databind() to the MenuClick event but if Monday has 3 pages, and they click on Tuesday which only has 2 pages, it would give me an error. Also the adding of the Databind() still doesn't fix the page index when I click on a different day.
How do I reset the page index when the user clicks on the day.

how to set the gridview page index to the recently created row,
when i add data using formview the grid view does get refreshed. but the page index returns to zero.
i would like to put some code so that the grid view page index displayed is that which contains the newly added row.
I have a gridview with paging. I have a style set for a selected row (highlights the row in light orange). What i would like to do is that each time a user chamges the page, the selectedIndex & selectedRow automatically becomes the 1st row of the selected page. So i would like to see the orange highlight on the 1st row of the page to indicate that the row has been selected.
I have tried GridView1.SelectedIndex=0 but this only seems to select the index of the 1st record in the whole datagrid. Does anyone know of how to set the 1st row of the page to the selected row each time the pageindex is changed?
