in ASP.NET 4, I have a GridView, which contains a DropDownList in the section. The DropDownList is populating with all of the options I need from a second data source. However, I would like to have each DropDownList in each row have a different SelectedIndex set on default based on data already in the GridView.
View 1 RepliesI have a question regarding the GridView and the Control Designer of it.
I've made a composite control inherited of the GridView. I would like to make some new created BoundField controls available in the designer of the GridView control? So that I can select the custom BoundField control from the Available fields list.
How to disable editing the data in the cells of datagridview in c#?
View 1 RepliesI have a GridView with a templatefield that contains a dropdownlist. I want to insert the selectedvalue as a datetime field into a table.
This is my code:
Protected Sub GridView1_RowDataBound(ByVal sender As Object, ByVal e As GridViewRowEventArgs) Handles GridView1.RowDataBound
If e.Row.RowType = DataControlRowType.DataRow Then
Dim shippingdate As DateTime

I am trying to populate a gridview when you select the dropdownlist.selected value. I don't want to use the sqldatasource or any other datasource. I am trying my best to achieve this, but didn't succeed till now. One of my friend said that i need to get the selected value from dropdownlist and search for the data in the database using the selectedvalue and populate the dataset and bind to the gridview.
View 2 RepliesTwo ddl inside gridview. on selecting first ddl1 fill next ddl2 by passing selected value as parameter by executing the sqldatasource select command in codebehind.code:
GridViewRow gr = (GridViewRow)((DataControlFieldCell)((DropDownList)sender).Parent).Parent; //find the control in that DropDownList d1 = (DropDownList)gr.FindControl(ddl1); DropDownList d2 = (DropDownList)gr.FindControl(ddl2); SqliaDataSource.SelectParameters.Add("@name", d1.SelectedItem.Text.ToString()); dataView dv=(dataview) SqliaDataSource.select(DataSourceSelectArguments .Empty);

I want to have a dropdownlist in the footer row of a gridview. The dropdownlist must be populated with an stored procedure that receives a parameter and has a select. Is that posible?? I think yes but I having problems with the parameters.
[Code]....
The exception says incorrect sintax... but I've changed the procedure for something very simple to solve the problem like select 'hello' or select 1, 'hello' and I'm getting the same problem...
protected void Button1_Click(object sender, EventArgs e)
{
System.Collections.ArrayList list = new System.Collections.ArrayList();
list.Add("abc");
list.Add("xyz");
list.Add("pqr");
list.Add("efg");
GridView1.DataSource = list;
GridView1.DataBind();
}
Now when data is bound to the gridview the column name is by default "Items" but I want to change the header text of this column.
I am binding a GridView using a DataSource in asp.net, and i would like to have some hidden BoundFields so I can access those values in my RowDataBound Function. However, when I set Visible="False" on these BoundFields the values do not get set and are always blank in the RowDataBound function.
I've seen some suggestions of setting the style on the BoundField to hidden but this did not work for me either. Ideally I don't even want a column created in the gridview, I just want these values to be hidden so I can access them.
I have a GridView like this
<asp:GridView ID="gv_FilesList" runat="server" AutoGenerateColumns="false" onrowcommand="gv_FilesList_RowCommand">
<Columns>
<asp:BoundField DataField="f_Id" Visible="false" HeaderText="File Name" />
</Columns>
<Columns>
<asp:BoundField DataField="f_Name" HeaderText="File Name" />
</Columns>
<Columns>
<asp:ButtonField ButtonType="Link" Text="Download" CommandName="DownloadFile" HeaderText="Download" />
</Columns>
</asp:GridView>
Now when I click on the download Button, how can I get the corresponding f_Id in order to get the related data from Database.
I have a grid view control having some bound and template fields as follows
<asp:BoundField DataField="ID" HeaderText="ID" InsertVisible="False"

<ItemTemplate>
<asp:LinkButton ID="btnques" runat="server" onclick="btnques_Click"
Text='<%# bind("Question") %>'></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
Now what I want to do is that on the click event of a buttom btnques, I want to access its corressponding boundfield ID's value and to store it in a label.

View 15 RepliesCan I do something like this:
<asp:BoundField DataField="Field1"
HeaderText='<% IF(Eval("Field2").ToString().SubString(3,4).Equals("Text3"),"Text1","Text2") %>'
SortExpression="Field1" />
With the goal of having the header of Field1 be Text1 when the 4th-7th characters of Field2 = Text3 and Text2 otherwise?
I tried it and it just put "'<%IF(Eval("Field2").ToString().SubString(3,4).Equals("Text3"),"Text1","Text2") %>'" as the actual header string!
i am having a boundfield column and in that column if i entered a string(without spaces) of length 15, there is no problem. But if the string is more than 15, the text is not wrapped. I gave the command column.ItemStyle.Wrap=true; But its not working. I have fixed the width of the column. How to wrap the text in the boundfield if a string more 15 characters.
View 3 RepliesWhen using a simple gridview targeting .net 4.0 if i click the edit button twice it converts to BoundFields to textboxes, but in previous version of .net (3.5 and 2.0) nothing happens (eventhough msdn says it suppose to happen). Have anyone seen this issue?

I'm trying to programaticaly change the 'headerText' property of a GridView boundfield.
[Code]....
Apparently all goes weel, because i ca see, in a a debug session, the control initial value, and after i change it, the value changes.
In vb.net how can I get the value of a gridview's boundfield value? I'm basically putting a value in that boundfield that I need to access in the RowDeleting event so I can pass that into a stored procedure. I'd be open to also trying to get the value of a control from a template column too if that's a better method?

I have a dropdownlist attached to a cell when edit is selected. I am using the following code to populate the drop down list with the value that is on the row.
dlBU.Items.FindByValue((e.Row.FindControl("lblBU") as Label).Text).Selected = true;
This works famously when I have a value in the cell. It fails when the cell has not yet been populated. Is there an if then clause that if the value of e.Row.findcontrol("lblBU") is null no default value?
I have seen this tutorials, its very good.
