I'm trying to loop through a manually created row's controls in a gridview and set the visible property.
I can use findcontrol and it works fine and I don't have to loop. But there are a lot of controls, so I just wanna do it in a loop. But it never finds the control type I'm looking for. Here's my code:

I have a gridview that is bound to a SQL datasource and is filtered via FilterExpression,
the FilterExpressoin is using Contro Parameters in a for of textboxes.
I want a certain button to become visible (btnInsert.Visible=true) when the filterExpression returns no results.
what event should I use? what is the code for that?
Im into a situation, where, I need to embed linkbutton to gridview to display one field (TITLE) from database. It was done as I've added it in the itemtemplate. Now my situation is bit refined; I should add a text box and another linkbutton which should be disabled on page load and when ever I click that linkbutton which is displaying (TITLE) should make the textbox and another linkbutton visible by displaying corresponding values from the database in the textbox.
View 5 RepliesHow do I loop through a GridView (the actual GridView, not its data source) to check what's displayed in the first cell (a BoundField with int data) of every row?
View 4 RepliesI would like to ask a question on the visual basic codes to loop the gridview to retrieve the values and based on the values, it will be provided as parameters to update to the database table using stored procedure.
Firstly, I have a gridview named grvProduct. The page (ui) will be loaded with data from the database with the use of stored procedures. And only certain values can be edited through the use of template in gridview. So based on those edited values, I'm supposed to pass these values as parameters to the stored procedure which will then update a database table.
Let say, I have 3 records retrieved from the database and displayed in the gridview. And I would like to edit a values in the 3 records, how do I do batch update and pass those parameters to the stored procedure? I went to debug and step through the visual basic codes and realised there were too many arguments specified because I actually loop the gridview.
Below is my visual basic codes:
[Code]....
Below is my Stored Procedure code:

I believe it is the error in the looping of the gridview which results that I could not batch update the data/values.
Is it possible to loop through a gridview and based on if a checkbox is checked, then change the backcolor to that current row? I have gave a few attempts, but luck.

I have a Bulk Gridview(all rows are editable) I need to loop through.I need to get the text that's displayed in each of the textboxes in the gridview, my current code is this:
[Code]....
like this, I need to loop through the gridview, but instead of just getting the text in each column, I need to get the text from the textboxes. How can I do that?If i'm going to use findcontrol() then I need the ID of each control. the gridview is always created dynamically, which means I don't know the number of controls that's being created beforehand. So, how/where can I find the ID?Is there another way to extract data from the textbox, other than findcontrol()?
I am just trying to view gridview that is inside other gridview but it is not visible although its visible = trure.

I have found demos of multi-edit gridview which basically mark each row as edited then loop through them:

I would like to avoid row by row loops for performance reasons possibly using the SQL Server 2008 "MERGE"
I program in VB.Net but I can use C#.
I need to make sure only one checkbox gets checked in a GridView. I have tried a solution on here, but I get an error. The other is looping through the checkboxes in the gridview to get the value, in this case, a date.

How do I loop the gridview to read or insert one row by one row?I have a database which has a Primary key. Currently,all the rows seems to appear at one time.Even when I use a counter,it did read one row from a textbox(which is for my testing to read one row) but in the database,it still inserts the whole rows from the gridview.I can't click button twice as it will occur an error "Primary Constraint".
View 6 RepliesI have a two gridviews that I populate it through some tables from a database.
In the same page I have a ASP:Button with onclick event.
When click is perform I wish to write a code that compares the old values of both gridviews (that retrieved from database), with the new values, and if changes were made then create the changes in the database.
I think that the best way is to loop every gridview sepertly, and compares it with the values in the database
How do I do that? Do you have a sample code that loops on gridview and compares with the old values to detect changes?
I have a code like yis
for(int i=0;i<Count;i++)
{
k=item(i);
}
I want to add each value of 'k' to a gridview..If I have 10 values for 'k' (count=10), then I want to display a gridview with 10 rows...How can I do this?..
I need to loop through a GridView and get the values of a databound field. Then use those values in my update statement.
Here is the GridView:
[Code]....
And here is my UPDATE statement, which is actually just passing the values to a stored procedure:
[Code]....
Right now, I just have it grabbing the text from a label control, but I know that will not work as it only passes one value. I need to be able to update multiple rows based on the del_doc_num.
I have a customized gridvew i.e. grvResult. There is a textbox and a InsertButton in the footer.
If there is a data populated into gridview it is showing GridView footer and inserting data but if there is no data in gridview then its footer also not visible.
I have tried in two ways to make footer visible but it is showing following error:
Object reference not set to an instance of an object.
Tried ways:

I have a master/detail page using a gridview as the master, and a detailsview as the details. The gridview is set to select a record, and the detailsview picks up the ID and you can either edit that record, or add a new one.The detailsview is set up with various template fields, and if everything on the page is visible, it works OK.However, I wanted to hide the Gridview when the user in working with the detailsview. But if I do that, the detailsview doesn't update the record.
View 2 Repliesi have a gridview inside a div that has scrollbars. see bellow
[Code]....
is there a way to keep the gridview header always visible while scrolling down.
like in MS Excel.
I am able to get the values of GridView cells when the columns are not visible.
For Example:
<asp:BoundField DataField="TemplateKey" Visible="false"/>
foreach (GridViewRow gvrow in GridView1.Rows)
{
gvrow.Cells[0].Text.ToString()
}
But if I make the BiundFiled Visible="true" then I get the value in the code behind.
I do not want to show this value to the user and also want to get the value in the code behind. How can I do that?
Whenever you turn off the visibility of a column in Gridview, on Edit, the value becomes null because its never bound. The only way I know of stopping this behavoir is to put it in the DataKeyName list. Is there any other way to prevent this? I have quite a few columns that will not be displayed in this "release" but I want there for future extensibility. Also, in some cases these values will be used for calculations but the user should not see them. Is there no toggle property for "non-visible" items to remain "unchanged" or something of the sort?

I have an Outer gridview (called grdvOUTERGRIDVIEW) and an Inner Gridview (called grdvOUTERGRIDVIEW) and I am able to see and use the outer gridview in my codep-behind vb page however when I try to handle an event for the Inner gridview then I get the warning: "handles clause requires a withevents variable defined in the containing type or one of its base types".
After creating the inner gridview I closed the page out and re-opened it however still getting that error and not able to create the grdvINNERGRIDVIEW.RowDataBound event function like I am trying to do.

I am having a strange problem. I put on a Gridview on my aspx page. I also data bound it to a table from my SQL server.
Other than that I wanted to put in the Edit, Update and Cancel functionality so I also put in this from the Gridview Smart Tag.
Following is the gridview aspx code can anyone tell me what I am missing here?

I my site there is grid view and the option auto generated column is true of gird view
At run time I am hiding and showing columns as user has set it.
I want to count visible columns at runtime but I am facing a problem to count
I have a GridView, the first column it's a RadioButton template and the second it's a DropDownList Template, the number of rows depends on the user, I mean they are not static. I'm using the following JS function to get the row selected with the radiobuttons:
[Code]....
With this function I know which RadioButton was selected, now, I would like to get the DropDownList value or text of the selected row, I know I have to loop through every DropDownList to get an array of controls, but since they are something like ctl00_ContentPlaceHolder1_GVProducts_ctl02_DValsDropDown, I just don't know how to achive this through JS.
I have a gridview in which I add extra rows manually (besides the regular bound rows).The manually added rows do not have a textbox, they are just text.The normal rows hold a textbox "minprice".Now when the user clicks the NewGarage button I want to loop through the gridview and get the values in each row for the minprice textbox.
Gridview structure looks like this:
MANUALLY_ADDED_ROW
NORMALROW <= enter value here works
MANUALLY_ADDED_ROW
NORMALROW[code]...
<asp:ButtonField Text="Void" ButtonType="Link" CommandName="Void" />
' RowCommand
Dim f_iIndex As Integer = Convert.ToInt32(e.CommandArgument)
Dim f_oSelectedRow As GridViewRow = grdMeterCorrection.Rows(f_iIndex)
Dim f_oCertIdCell As TableCell = f_oSelectedRow.Cells(11)
Dim f_sCertId As String = f_oCertIdCell.Text.Trim
If e.CommandName.ToLower = "void" Then
Dim f_bVoidRet As Boolean = VoidCert(f_sCertId)
End If
The problem is the CertId field in the GridView has visible set to false. I think this makes the value unaccessable to the RowCommand.
