I have a nested gridview dynamically added. It seems I resolved all issues with the loading this control on a parent page along with other controls and I can trigger the edit of the first level - the master part of the gridview. However, I cannot trigger the edit on a child gridview.
OnRowEditing="grdChildGridEdit_RowEditing"
The master and the child gridviews have objectdatasources in a markup but I have to do the additional data binding after the loading the control on the parent page (see the code below). I'm doing that additional data binding only for the master gridview that is working fine and shows the data for the master and the child gridviews. When I click the Edit button on the master gridview it shows text boxes for the editing but when I click the Edit button on the child gridview it's doing nothing and moreover the editing mode for the master gridview is going back to the initial stage (labels).
I was trying to trigger it throughuse the registering the event:

In my table I have 3 fields:
[inFrmDate] (this is the key field), [inFrmData], [totFrmData] (this accepts nulls)When I try to add [inFrmDate], [inFrmData] to the GridView I get the messageto the effect that the:
@inFrmDate scalar is not declared.
But as you can see from below it is declared:
<asp:SqlDataSource
ID="SqlDataSource1"

View 1 Replieshow to place newly added or edited row at the top in the gridview
View 3 RepliesI have an image button in my gridview which I'm using to open a new window.
The code for my image button is:
[Code]....
This works fine, in that a new window is opened correctly, however, clicking the button causes a blank row to be added to the top of my grid.
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

I'm dynamically adding a DropDownList to the GridView in edit mode and I have set the TextBox Visibility to False. In edit mode I can see the DropDownList and I'm able to select an Item from the DropDownList but not able to access the SelectedValue in RowUpdating Event. How to get the selectedvalue of this DropDownList?
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As System.Web.UI.WebControls.GridViewRowEventArgs) Handles GridView1.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow And (e.Row.RowState And DataControlRowState.Edit) > 0 Then
Dim ddl as DropDownList
FillStateList(ddl)
e.Row.Cells(4).Controls.Add(ddl)
ddl is the DropDownList that is added dynamically. And the default Textbox that is in the Edit mode is set to invisible. So there are actually two controls in the same cell in edit mode(TextBox is invisible).
DirectCast(Gridview1.Rows(e.RowIndex).FindControl("ddl"),DropDownList).SelectedValue
If I use the above statement I'm getting NullException.This is Probably because its a BoundField. Is there a way I can access the DropDownList 'ddl' SelectedValue?
I am working on a Webbased project, where we have a Master page with some child page. In the child page there is GridView control, Footer of this Gridview control have some TextBox control to get the input value from user and insert into database. Once the data is inserted into database. We are reloading the inserted data into the same Gridview control, But Gridview control is hot Binding/showing up the recently added record.
I debugged the code and seen the Dataset which is getting the data fron database have the updated row but after binding to Gridview control. The Gridview control not refreshing the data. This is happening while we have Master page and child page.
i am using c# and want to do a validate to edit and do a new fild.
View 7 RepliesI have a SQL table containing a timestamp column. This table is displayed in ASP using GridView control. The timestamp column is indicated in the DataKeyNames property of the GridView. I'm using TemplateFields for all columns and a ItemTemplate HiddenField control connected to the timestamp column using Eval.
<asp:TemplateField
ItemStyle-Wrap="false"
Visible="false"
HeaderText="timestamp"
SortExpression="timestamp">
<ItemTemplate>
<asp:HiddenField
ID="gv_hid_timestamp"
runat="server"
Value='<%#
Eval("timestamp") %>'
></asp:HiddenField>
</ItemTemplate>
</asp:TemplateField>
The data is displayed properly. I'm trying implement the optimistic concurrency in C# using the value of above mentioned timestamp and a stored procedure. The SQL stored procedure expects the @timestamp as varbinary(8). I'm not sure how to pass the value of gv_hid_timestamp back to the stored procedure. I'm using the following:
command.Parameters.Add("@timestamp", SqlDbType.Binary).Value = Byte.Parse(((HiddenField)gv.Rows[row].FindControl("gv_hid_timestamp")).Value);
resulting in the following error: "Input string was not in correct format." (I also tried different data types but with similar result). I want to be able to pass this parameter programmatically from C# and not have to specify it on the UpdateParameters list.
All of my columns are bound in the Gridview. On OnRowDataBound event, I am adding some custom styles like underlines and colors to the text of the columns. Sorting of data is working fine but I am losing my custom styles when I sort. I am using the generic sorting code for the GridView.
How I can keep my custom styles on sorting that I added during OnRowDataBound event.
I need to validate and read edited values from a gridview. Here is the scenario,I have a gridview which has two columns Iteam name and Item Rate. Number of rows are dynamic depending on the user. I get the Text boxes filled with DB data.
I need to do this,
1) Validate if the user has entered numeric using front end validation
2) Read the edited values by user for each row and insert into the database in server side

How to validate user entry to cell in GridView and replace the cell value on the other column?
Ex :
i have a gridview with 2 columns (A & B), on both columns i change it to TemplateField (TextBox).
Now on whatever row on column A, i want to validate the user entry when user leave the cell, how to achieve that ?
Based on user entry on column A, i will do some data lookup and get a value returned from the server, how to tell the gridview to replace the value on column B (on the same row) based on the value returned from the server.
I am working with VWD Express and Visual Basic. take this into consideration if you are willing to answer my question. I do have the following code for a GridView.
<asp:GridView
ID="OpenCloseUDTIGameThreadGridView"
runat="server"
AllowPaging="True"
AutoGenerateColumns="False"
DataKeyNames="AutoNumber"
DataSourceID="OpenCloseUDTIGameThreadSqlDataSource"
CellPadding="4"
ForeColor="#333333"
PageSize="100" >
<Columns>
<asp:TemplateField HeaderText="Picture">
<ItemTemplate>
<asp:ImageButton
ID="ThumbNailImageButton"
runat="server"
Width="75px"
PostBackUrl='<%# string.Concat("~/Classifieds/DetailPage.aspx?AutoNumber=",Convert.ToString(Eval("AutoNumber")),"&FlagForm=NoSubmitted") %>'
ImageUrl='<%# IIF(System.IO.File.Exists(Server.MapPath(string.Format("~/UploadedImagesClassifieds/{0}{1}", Eval("AutoNumber"), "Pic1.jpg"))), string.Format("~/UploadedImagesClassifieds/{0}{1}", Eval("AutoNumber"), "Pic1.jpg"), "~/UploadedImagesClassifieds/NoPicture.gif")
%>' />
</ItemTemplate>
<ItemStyle HorizontalAlign="Center" />
</asp:TemplateField>
<asp:CommandField ShowEditButton="True" />
<asp:BoundField DataField="TCategory" HeaderText="Category" ReadOnly="True" SortExpression="TCategory" />
<asp:BoundField DataField="TItemTitle" HeaderText="Item Title" SortExpression="TItemTitle" ReadOnly="True" />
<asp:BoundField DataField="TUDTIThreadActualStatus" HeaderText="Actual Status" SortExpression="TUDTIThreadActualStatus" />
</Columns>
</asp:GridView>
As you can see the second cell in each row is a EditButton, and the only cell that could be updated by users is the last one, DataField = TUDTIThreadActualStatus. I just want to know what could be the easiest way to validate the user entry when the row is in edit mode. Is there anyway to validate the textbox control with a validation control or is better to used code behind. Either way may you explain and drop some code if posible.
I am using a gridview that contains an asp:fileupload so that when the user clicks 'edit' they can upload a pdf. I need to validate the size of the file, it needs to be less then a certain size. I tried to use a custom validator, but it never get called when the user updates. How can I validate the file size on edit in the gridview?

This is my gridview structure I need two things from this1) For example in Label1 shows 50 then In Text1 I need to check the value is less than or equal to how to validate in client side in adp.net validation or javascript...? Like this same for second Item template also I need validation.. Like this I have some 10 itemteplate....2) On button click I need to save the value of Text1 and Text2 in database.. how would be my Insert statement in button click..
I have a gridview each line has 4 linkbuttons - Edit , Update , Cancel , Delete and a few columns with data...For example TeamName and TeamEmail, and a hidden column that contains a validator (for ease of validating controls that are found on the same row , same naming container)
When Edit button is Clicked , the specific line goes into editing mode , Texboxes are created for TeamName and for TeamEmail .
I create dinamically (code behind ) a new textbox that reads the value from the TeamEmail textbox , i give it a new id (let's say "Email") , add that email to the controltovalidate property of my validator , and call the validate() method of the validator.
Everything works fine when i modify the value in a worng format , the validator err message appears , when i modify the TeamEmail value to a good email format , the validator property isvalid becomes true , and the update is running , but my textbox is empty :( updating the TeamEmail value to null.
This is some bad code but hope you understand what i meant :
This is my html coed of my gridview

View 2 RepliesI'm trying to validate that a GridView logated in one of the steps of the Wizard Control is populated by the user before the Next button is clicked. What I mean is that I need to block Next (or Prev) button until the user populates a gridview, once the gridview has at least one element then enable the (Next/Prev) buttons. How can I enable/disable Next/Prev buttons within a specific step?.
