I have a manual binding to a grid view. After that, I found out the Grid_View.Columns.Count still give me 0.
I tried to set this:
AutoGenerateColumns="False"
After I set this value, the gridview become empty. Wonder if the False causing the column count to be 0.

I have a gridview bound to a SQL Select statement. I want the binding of one of the columns to depend on one of the values in the database record. For example, say I have a SQL table containing FirstName, LastName, ShowFirstName.
I want a the Name column in my Gridview to be bound to FirstName if ShowFirstName is 1, and bound to LastName if ShowFirst Name is 0.
how to bind data in an ItemTemplate column in my Gridview.
I have created an ObjectDatasource on my page bound to my Gridview using a Dataset from my linked SQL tables (PKs, FKs,etc...).
I am showing all my USERS table data in my Gridview but there are some columns which are ID's being displayed such as MembershipID, UserTypeID. These ID's are my foreign keys to other SQL tables.
I have easily been able to go into my EditTemplate for these columns, attach a new ObjectDataSource as a Lookup table, add a new DropDownList in place of the TextBox and then set Two-way binding so that the MembershipName & UserTypeName's are displayed for editing.
However, I cannot seem to work out how to do this Binding to the other ObjectDataSources in the ItemTemplate Label. Again i can make it work witha DDL, but i don't want any selections when just displaying the data in the Grid. I simply want the name to be shown in a label, but cannot work out the binding lookup?
I have a web page with an object data source that is connect to an object access layer which retrirevs an Id, Name_En and Name_Local from some table, the object data source is connected to a GirdView, In the girdview i have a template control with a label inside it, i want to change the binding expression for the label depending on the current states of localization so for example if the page is arabic the label should bind to "Name_Local", if it's english then it should bind to "Name_En"
View 1 RepliesI have a FormView that I user for updating a record. There is a link button that when fires should perforom the updating via BLL and DAL. I am not using built-in ODS and I will not condsider using it. I have all my grids and formviews populated manuualy by calling methods that fetch the data from the database. For instance my details view is populated like this:
protected void DlMembers_ItemCommand(object source, DataListCommandEventArgs e)
{
if (e.CommandName.ToString() == "Select")
{
DlMembers.Visible = false;
lblError.Text = string.Empty;
lblError.Visible = false;
fvMemberDetail.Visible = true;
fvMemberDetail.ChangeMode(FormViewMode.Edit);
MemberBLL getMemberInfo = new MemberBLL();
int Ident = Convert.ToInt32(e.CommandArgument.ToString());
fvMemberDetail.DataSource = getMemberInfo.GetMemberByIdent(Ident);
fvMemberDetail.DataBind();
}
if (e.CommandName.ToString() == "DeleteSelected")
{
DlMembers.Visible = true;
lblError.Text = string.Empty;
lblError.Visible = false;
fvMemberDetail.Visible = false;
fvMemberDetail.ChangeMode(FormViewMode.ReadOnly);
}
What I want to do if to capature my linkbutton on click event and do this (except that the runtime never reaches this method):
protected void MemberInfoUpdating(object sender, EventArgs e)
{
TextBox id = (TextBox)fvMemberDetail.FindControl("txtIdent");
if (id.Text != string.Empty || id.Text != "")
{
TextBox txtFN = (TextBox)fvMemberDetail.FindControl("txtFN");
TextBox txtLN = (TextBox)fvMemberDetail.FindControl("txtLN");
DropDownList ddlAddress = (DropDownList)fvMemberDetail.FindControl("ddlAddress");
TextBox txtEmail = (TextBox)fvMemberDetail.FindControl("txtEmail");
TextBox txtHPhone = (TextBox)fvMemberDetail.FindControl("txtHPhone");
TextBox txtWPhone = (TextBox)fvMemberDetail.FindControl("txtWPhone");
TextBox txtMPhone = (TextBox)fvMemberDetail.FindControl("txtMPhone");
DropDownList ddlPos = (DropDownList)fvMemberDetail.FindControl("ddlPos");
DropDownList ddlIsAdmin = (DropDownList)fvMemberDetail.FindControl("ddlIsAdmin");
bool blIsAdmin = false;
if (ddlIsAdmin.SelectedValue == "True") blIsAdmin = true;
TextBox txtComments = (TextBox)fvMemberDetail.FindControl("txtComments");
MemberBLL updateMemberInfo = new MemberBLL();
bool UpdateOK = updateMemberInfo.UpdateMemberByIdent(
txtFN.Text,
txtLN.Text,
ddlAddress.SelectedValue,
txtEmail.Text,
txtHPhone.Text,
txtWPhone.Text,
txtMPhone.Text,
blIsAdmin,
txtComments.Text,
Convert.ToInt32(ddlPos.SelectedValue),
Convert.ToInt32(id.Text));
}
else
{
//Display error - no user id cannot update record
}
}
The linkbutton looks like this:
<asp:LinkButton ID="UpdateButton" runat="server" CausesValidation="True"
OnClick="MemberInfoUpdating" Text="Update" />
I have a Formview binded in the code file to a generic list. Now, upon editing of a record, I wish to access the Keys and NewValues out of the FormViewUpdateEventArgs parameter of the ItemUpdating event handler method. From what I've tried and searched over the internet as of now, I've come to know that updated values are only available if the Formview is set a data source control on the markup page else they'd be null. Is this true?
Secondly, at this moment I am casting the sender object to formview and individually filling each object property by using FindControl method to find and retrieve values present in the controls. Is this the best way to do this task? As an example, this is what I am doing atm:
FormView currentForm = (FormView)sender;
ListObject.ID = new Guid(((HiddenField)(currentForm.FindControl("hdnID"))).Value);
ListObject.Name = ((TextBox)(currentForm.FindControl("txtName"))).Text;

I want to dynamically bind dataset values into datagrid's header datafield.
Is it possible? To be more clear, when you click on datagrid's (Collection) from properties window, you get selected columns created from Bound column. So in those columns I want to dynamically display dataset's table values in those columns.
i.e like ds.Tables[0].Rows[0][0].
Is it possible to do it in Datagrid ItemDataBound function like,
e.Item.Cells[1].Text = ds.Tables[0].Rows[0][0]
or something like this? I know the above code is wrong and wont work since I tried it out and while building it throwed error saying, Cannot implicitly convert type 'object' to 'string'.
