Iam having a gridview with textboxes in itemtemplate. If textbox validation fails whiling clicking the submit button gets into exception and loses its rowindex values. Based on the row index value iam setting theme for gridview rows. So when i click the row it throws null value exception. I dont wanna bind grid in catch block, since i have to maintain the values user entered in the textboxes)
View 1 RepliesI have a dropdown list inside a gridview:
[Code]....
gvOff.DataSource = o.ViewData(dCity.SelectedValue);
gvOff.DataBind();
gvOff.Columns[0].HeaderText = "ZZZZZZZZ";
gvOff.Columns[1].HeaderText = "YYYYYYYY";
gvOff.Columns[2].HeaderText = "XXXXXXXX";
Header count is correct.
AutoGenerateColumns: Flase/True ( i tried both)
If i remove the gvOff.Columns[index].HeaderText portions, GridView works fine, but when i put the gvOff.Columns[0].HeaderText, i get the exceptional error.
, i couldn't solve it. If you need further info, inform me.
EDITED:
Hold on! I commented the HeaderText portion and tested
int i = gvOffer.Columns.Count;
I found count is 0 eventhough the columns print out with DataBind()... Why?
NOTE: AutoColumn in this case is set to true. I guess i will have to edit the column
names from DataTable.
i have a global field called hotelId. i then have this piece of code that gets a value from gridview row:

the local variable is assigned to my global one, which gets passed to my method along with other variables. while stepping through i can see the value is set, but when i hit the submit button variabl is passed to another method except my hoteId. it gets lost...
I have a gridview with auto Edit buttons... when I click on Edit button it is losing it row and column colors.We are initially setting the gridview colors in the page_load event.
View 3 RepliesI have the following gridview...
[Code]....
And inside that gridview you can see I have a dropdownlist called dpdTrueFalse. That dropdown has two values which I am loading from code behind like this...
[Code]....
I have a submit button outside that gridview that checks each row and the selected value in the dropdown. But for some reason, even if you select another item in the dropdown, it always selects the first item in the dropdown when I click the submit button. I reckon its because of the postback.
I have a GridView that I want to export to Excel. When I use the sample code I find online, it exports the content to Excel just fine, but for some reason it also clears out all grid lines outside of my exported table.
For your average excel user this is easy enough to fix, but I need this solution to work for everyone.
So then is there a way to export the data in a GridView into an Excel Workbook so that it looks like it was just typed into Excel? I've pasted the code I am using below, assume that a GridView called toPrint exists and has accurate data.
Response.Clear();
Response.AddHeader("content-disposition", "attachment; filename=" + name + "_Registration_Forms.xls");
Response.Charset = "";
Response.ContentType = "application/vnd.ms-excel";
Page.EnableViewState = false;
System.IO.StringWriter stringWrite = new System.IO.StringWriter();
System.Web.UI.HtmlTextWriter htmlWrite = new HtmlTextWriter(stringWrite);
toPrint.RenderControl(htmlWrite);
Response.Write(stringWrite.ToString());
Response.End();
EDIT: Found one partial solution. If I export as a comma-delimited list and set the header to be a CSV file, it opens fine and all grid lines (even those outside of the exported data) are showing. The only problem with this of course is having to strip out every comma and newline character from my values before exporting them.
I have a page I use to update a student's personal and grade information. I use a formview control to enter and update a students personal information. I use a gridview control to enter and update the student's grades. When the user wants to make edits to the data, they make the changes in the formview and the gridview, then press a "Save" button, which runs code behind that reads the formview and gridview data, builds two SQL UPDATE statements, then performs the update on two SQL tables (the Students table and the Grades table). This seems to work fine in most cases.
View 1 RepliesI'm working on a project where we're using Windows Desktop Search (WDS) to index files on a web share and then later allow the user to search via a website for documents in the share.
These documents are transferred to the share via FTP, however it would seem that either the computer never goes idle to index or at some point the indexing stops. Is there a way from the command line or within the program itself to force this to happen without having to re-invent the wheel? Using .NET 3.5 and C#.

chk.Checked = true;
strCelValue = chk.Checked.ToString();

How to set my gridview page index on load ?. I have two pages, one for selecting the record and one for updating. Oh, and btw in those 2 pages i also have 2 gridviews. So anyway, what im trying o do is if I select a record in the first page (lets say 2nd row at 2nd page index of the gridview) I want that if I redirected it to the second page the selected record should be selected on what page index of gridview it is.
I figured out how to select the row of the selected data using the Gridview.SelectedIndex. My only problem is the page index of the gridview. If the selected data were belong to the second page index the page index of the second gridview (wherein the second page) must be selected. How to do that ?

View 1 RepliesIn my gridview when the tab button is pressed the RowDataBound event is fired and I can capture the tab event. But if there is no data in the gridview textbox and tab is pressed, the RowDataBound event is not triggered. Is there a way to capture that event?
View 1 Replieshow to get the cell index of gridview in the event selectindexchanged?
View 4 RepliesI have a gridview and the OnRowDataBound event is linked to this function:
if (e.Row.RowType == DataControlRowType.DataRow)
{
ThisRow = e.Row.DataItem as MyObjectModel;
if (ThisRow.Property1 == null) { e.Row.Cells[5].Text = "-"; }
This code looks at the value of a property of the object in the data source and if it's null, converts the null to display "-" in column 5. The problem I'm having is that if I change the order of the columns of the gridview, then I need to change the index of every other modification. What I'd like to do is change the statement "e.Row.Cells[5].Text" to something that says "the cell whose column header is xyz".
