I have a gridview that is being databound by an SQLdatasource and on RowDataBound i am doing a calculation and then setting

Forms Data Controls :: GridView Control Cell Turns Grey When Updating Cell?

Feb 11, 2010

I'm having a weird problem where the GridView cell that I'm programmatically updating turns grey, and throws a null error when attempting to save row. I have been searching all day and have not been able to find a solution. I'm guessing there is a problem with my code, so here it is:

Forms Data Controls :: Getting Row In Gridview Of Changed Template Item?

Jun 26, 2010

I have a dropdownlist as a template item in a gridview - it populates fine and with the right values. I have an SelectedIndexChanged on the dropdownlist, and has set it for postback. In the SelectedIndexChanged event, I would like to know where the control that fired this event is, - which row in the gridview is it in? How do I get this info? If the row was selected it would be easy, but the only thing that has happened in that row is that the dropdown has changed value and consequently the SelectedIndexChanged event has been fired - is that enough to know which row the event has been fired from?

Forms Data Controls :: Gridview With Save Button - How To Tell If A Row Changed

Feb 1, 2011

I have a Gridview with about 6 templated columns hooked up to SQL, with a Save button below the grid.

When save is clicked, I loop through each row, and write each row back out to SQL.

Can you recommend a good way for me to tell whether the row has changed so I can avoid re-writing the row when nothing has changed?

This is not only for performance, but I also have a request to write out a "Last Modified Date" along with each record. So for that, I would need to know whether the row has changed.

I saw someone mentioned that the Gridview.RowState could be used for this, but I don't see how.

One alternative I see is to re-read each row from the database first, to see if anything changed. Another alternative might be to set a dirty-bit on each Textchanged, SelectedItemChanged, etc, for the row, but I'm not sure where to store that.

Forms Data Controls :: Log Exactly What User Has Changed In Gridview Event?

Oct 13, 2010

I have Gridview which allows user to edit record.I already build the event to save the new record, time and user machine information to a log database.However, this means a whole record is saved to the log... if the user just change one or two column/field out of say 20 fields, then there is a lot of waste. Also the change is not obvious.How can I log exactly which field(s) was changed in the record ?

Forms Data Controls :: Gridview View Changed On Click?

Oct 22, 2010

Need to have the ability to change the view of my gridview based on button click, the easiest i can describe what im trying to do and need is if you have every been on any e-comm site where you get a list of items presented to you.. normally you may get a thumbnail, description and price.. but at the top of that list you get the option to view it as a list with no thumbnails and so on..

Is gridview the best control to be using if i want to do that? example of what im needing is similar to walmart.com

if you search for a product doesnt matter, when the results are presented to you, you have it in what they call "List View", but you have the option to view it in "Grid View", not sure if they are actually using listview and gridview controls.. but i want the same end results..

What would i use or what can i search on to accomplish the same thing.

Forms Data Controls :: Select 1st Row In Gridview When Page Index Changed

Jan 14, 2010

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?

Forms Data Controls :: How To Set Height And ItemSource (Business Object As DataSource For Cell) For Every Cell

Mar 24, 2010

How to set Height and ItemSource(Business Object as DataSource for Cell) for every Cell in DataGrid/ Grid? Shown below is part of code I am currently using with Grid Control. What I am currently doing is that I am using ListBoxItem, set Item Height and ItemSource at ListBoxItem Level, Add ListBoxitem to ListBox and then Add ListBox to Grid, It leaves me with just one row and multiple columns in the Grid, which is perhaps not the best way of doing it as it doesn't allow me to take benefits from UI Virtualization of Grid.

[code]....

I am open to use any control i.e. Grid/ DataGrid provided it allows me to set Cell Height and item source at Cell level. In my requirement, Cell height depends on the Item duration and size of image, which means the height of the cells may not be same across cells in any particular row.

Forms Data Controls :: Gridview Attribute Changed By Javascript Is Lost On Postback

Sep 10, 2010

I have a gridview control that extends the default gridview. I have added an attribute called "hiddenSelectedValues" to to the gridview during the "PreRender" event and I have a private variable that points to the value of that attribute.

I have some javascript code that modifies the value of this attribute based on the user checking or unchecking checkboxes in the grid. I have confirmed that the javascript is indeed modifying the value of the "hiddenSelectedValues" attribute by using Firebug to see the change as it happens.

However, once a postback occurs, the grid looses the updated value of this attribute and I am unable to reference get the updated value on the server side.

How do I keep the value of an attribute changed by javascript on postback?

//proceed only if the Details button is clicked...
if (e.CommandName.ToLower() == "details")
{
//Get the row index selected...
int index = Convert.ToInt32(e.CommandArgument);
GridViewRow row = grid.Rows[index];
