Nested Gridview Footer Textbox Required Field Validation Firing for Each Row on Nested Gridview Footer Button Click

I am trying to get the required field validation to fire only for the specific row when the add button is clicked. But right now, when I click any add button, it fires the required field validation for all nested grid rows. The code for the nested gridview and the image of the gridviews is the following. I also tried to use validation groups, attempting to get unique validation groups for each nested gridview row, but couldn't get it to work.

For the validation control of each row you are adding the ValidationGroup='<%# "PC" + Eval("ContractProjectCodeID") %>'. As you are saying, that the validation triggers for the wrong row, it could be that ContractProjectCodeID may not be unique for each row. I think what you can do is add row index to the validation group
ValidationGroup='<%# "PC" + Container.DataItemIndex + Eval("ContractProjectCodeID")

How to set the width of TemplateField column in Grid view?

Hi I am developing a website using c# and asp.net. But my grid view is not showing properly for one page only. Whether I am using the same css class but still the output is something odd.
Here is the output I am getting:
here is my design view code for the grid:
<div style="width: 800px; align-content: center;">
<asp:GridView ID="gvMv" runat="server" AutoGenerateColumns="False" width="400px"
OnRowDataBound="gvMv_RowDataBound" CssClass="Grid" ShowFooter="True">
<FooterStyle Height="25" />
<RowStyle />
<PagerStyle />
<HeaderStyle />
<Columns>
<asp:BoundField DataField="day" HeaderText="Day" HeaderStyle-Width="150" ItemStyle-Height="25" HeaderStyle-Height="30">

<AlternatingRowStyle BackColor="White" />
</asp:GridView>
</div>
I want all of the column to be same width. Can anyone please help me on this?
Thank you.

I had the same issue and this is what worked for me
<asp:TemplateField ItemStyle-Width="150px" HeaderText="ABC" ItemStyle-HorizontalAlign="center">
<ItemTemplate>
<asp:Label ID="ABC" runat="server" Text ='<%# Eval("ABC")%>' ></asp:Label>
</ItemTemplate>
<HeaderTemplate>
<asp:TextBox ID="txtBusinessGroup" runat="server" onkeyup="filter_BusinessGroup(this)" CssClass="texbox_header" Width="130px" placeholder="ABC" Text="" ToolTip="TYPE IN THE ABC PLEASE"></asp:TextBox>
</HeaderTemplate>
<ItemStyle HorizontalAlign="Center" Width="150px" />
</asp:TemplateField>
I am showing textfield in the headertext which you can remove.
The width of the fields i change from
<ItemStyle HorizontalAlign="Center" Width="150px" />
or the actual textbox im using or the templatefield
<asp:TemplateField ItemStyle-Width="150px" HeaderText="ABC" ItemStyle-HorizontalAlign="center">
I hope this helps you and works for you or anyone else who might end up here.
thank you

Here is an example how you can do it :
<asp:TemplateField HeaderText="used">
<HeaderStyle Width="100" />
<ItemStyle Width="100" />
</asp:TemplateField>
You can use ItemStyle to set properties for your template field column

Try using this template code:
<asp:TemplateField HeaderText="ABC">
<ItemTemplate>
<asp:Label ID="lblABC" runat="server"
Text='<%#DataBinder.Eval(Container.DataItem, "ABCId") %>'>
</asp:Label>
</ItemTemplate>
<ItemStyle Width="20px" />
<HeaderStyle Width="20px" />
<FooterStyle Width="20px" />
<EditItemTemplate>
<asp:Label ID="lblEditABC" runat="server"
Text='<%#DataBinder.Eval(Container.DataItem, "ABCId") %>'>
</asp:Label>
</EditItemTemplate>
</asp:TemplateField>

i experienced the same. ItemStyle is not working! use HeaderStyle.
GridView1.Columns[2].HeaderStyle.Width = 20;

``If these all above code will note work to increase the width of gridview header then you can try this one also it will work definitely.Simply after YourText putt HTML space tag that is that much how much space you want.
**HeaderText="YourText "**

gridview sort order changes when editing row

i have a gridview which simply displays records based on a filter from a dropdownlist, when i change the dropdownlist the page postbacks fine and the filter works, but when i click to edit a row the sort order changes based on the new filter. when i change the drop down back to the original filter and click edit the sort order remains the same.
any ideas?

If you are rebinding the data into the Row_Editing event then you need to filter that with the drop down selected value.

Get value from DetailsView to FormView Textbox in insert mode

I'm trying to get the value from detailsview to formview. I want to set the Book ID/ISBN in formview insert textbox to Book ID/ISBN value from detailsview.
Here's a sample of my code:
<asp:DetailsView ID="DetailsView1" runat="server" AutoGenerateRows="False"
CellPadding="4" DataKeyNames="bookid" DataSourceID="detailsDataSource"
ForeColor="#333333" GridLines="None" Height="50px" Width="">

<RowStyle BackColor="#EFF3FB" />
<Columns>
<asp:BoundField DataField="EmployeeID" HeaderText="Reserved by"
SortExpression="EmployeeID" />
<asp:BoundField DataField="reservedate" HeaderText="Reserved date"
SortExpression="reservedate" />
</Columns>
<FooterStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
<PagerStyle BackColor="#2461BF" ForeColor="White" HorizontalAlign="Center" />
<SelectedRowStyle BackColor="#D1DDF1" Font-Bold="True" ForeColor="#333333" />
<HeaderStyle BackColor="#507CD1" Font-Bold="True" ForeColor="White" />
<EditRowStyle BackColor="#2461BF" />
<AlternatingRowStyle BackColor="White" />
</asp:GridView>
<asp:FormView ID="FormView1" runat="server" DataKeyNames="reservationid"
DataSourceID="reserveDataSource">
<EditItemTemplate>
reservationid:
<asp:Label ID="reservationidLabel1" runat="server"

<br />
bookid:

</EditItemTemplate>
<InsertItemTemplate>
Book ID/ISBN:
<asp:TextBox ID="bookidTextBox" runat="server"
Text='<%# Bind("bookid") %>'/>
<br />
Employee ID:
<asp:TextBox ID="EmployeeIDTextBox0" runat="server"
Text='<%# Bind("EmployeeID") %>' />
<br />
Reserve date:
<asp:TextBox ID="reservedateTextBox0" runat="server"
Text='<%# Bind("reservedate") %>' />
<br />
<asp:LinkButton ID="InsertButton" runat="server" CausesValidation="True"
CommandName="Insert" Text="Reserve" />
<asp:LinkButton ID="InsertCancelButton" runat="server"
CausesValidation="False" CommandName="Cancel" Text="Cancel" />
</InsertItemTemplate>
So what I'm trying to do is when a user click the Insert/Reserve book linkbutton the Book ID/ISBN is already set to the Book ID/ISBN in formview insert mode as default.
Any help would be much appreciated ;)
Thanks in advance.

Can you try and check the DetailsView1.SelectedValue
<asp:TextBox ID="bookidTextBox" runat="server"
Text='<%# DetailsView1.SelectedValue %>'/>
Edit:
Now if you want to bind that value to your Insert function of your DetailsView, it will not behave like the other control, since you are using the Bind method for the other control and it provides two way binding.
Now you need to pass that value to inserting evet of DetailsView like as we are assigning values using DetailsView1.SelectedValue but not binding the value.
I hope you understand this theory.
protected void DetailsView1_ItemInserting(object sender, DetailsViewInsertEventArgs e)
{
e.Values["bookid"] = ((TextBox)DetailsView1.FindControl("bookidTextBox")).Text;
}
