View 3 RepliesI have a listview control which is bound to DataTable object. When a user clicks "Add", I am creating a new row in the underlying datasource and refreshing the datatable so that it includes the new row and displaying the listview. My requirement is to "select" the newly added row after listview is refreshed. I have the ID of the newly created row and it is bound as one of the columns in the datatable.Now my question is, how can I get the index of that particular row which was newly created from the Listview so that I can set its SelectedIndex.

i have got grid view with 4 coloums which contains 2 dropdown list. n i have 2 drop down list out side the gridview .
i want to change the index of the 1st coloum dropdown list inside the gridview when changing the drop down list index outside using javascript
similarly the when the 2nd dropdown list(out side ) index change the 2nd coloumn dropdown list in gridview should change.
In short the outside placed dropdown list should act as master dropdown list.
i have two dropdownlist, second dropdown populates based on value selected in first dropdown.
Parentdropdown is working fine and second dropdown is also popualting correctly. But when i select value from second dropdown and click on submit button it resets to first value i.e though i have chosen 3rd value from dropdown it resets to first value.This happens when autopostback is not thr.
If for the same case ifi do autopostback=true. It chnages to first value automatically . then it odesnot require submitbutton click as well.
In both cases selected index is not getting set for second dropdown.

I am developing page for maintaing employee record using Visual Studio 2008, MS SQL server 2005. I am able to fetch and display all the employee information in gridview, the gridview have the dropdown list to display the employee type [ Part Time, Full Time, Permanent , Contract ], in the item template i am having dropdown list. IN the dropdown list i am displaying this. But While saving the record in gridview the droppdown selected index are changed to 0 of other dropdown list.
the user may be change the dropdown value from permanent to contract, or so. but while click on the save button in gridview, all the previous selection are gone, and always showing the first record of dropdown list. I know this is happening because we are doing dropdown list bind on onRowDataBound.

View 3 RepliesI have a column in SQL Server 2008 called MapLocation which is stored as the geography data type. This column is used to store the location of a building in one table, and the location of landmarks in another table. I have to list all landmarks within 4 miles of a building.
I have a clustered primary key on an automatically generated int column in each table. I assume that I need to create a spatial index on the MapLocation column in the landmarks table. This I guess would aid finding all landmarks within 4 miles.
My problem is that I am not sure what settings to use for this spatial index. I have set the spatial index to have the following settings:
Cells per object: 16 Level 1: Medium Level 2: Medium Level 3: Medium Level 4: Medium Tessalation Scheme: Geography gridAre these the best settings? Am I doing the right thing?

View 3 RepliesWe are developing our application on a 64 bit server. We are using a dropdownlist to filter and display departments in a htmltable(hide and show rows) on every selectedindexchanged event.
The issue is it is firing properly for the first time, but it is not doing a post back there after. We have even given autopostback=true. We are using AJAX for hiding and showing the rows of the htmltable.
I am having a label to show success message during the successfully save.
I am having a drop down with the name "Technology".
During on selected index change event of the drop down, i am binding another drop down with the name "Resources".
When the Button is clicked, i am showing the "success message" and on click event of the drop down, i am clearing the message by using the java script.
function ClearErrorMessage() {
document.getElementById('ctl00_ContentPlaceHolder1_lblMessage').innerHTML = '';
}
But when i change the drop down, the message gets reappeared.
