i'm using a GridView and trying to sort and page it.
I have more than 20 rows on my DataBase, but the GridView just shows 10.
I set AllowPaging=true but noting happened.
Also I'm using AllowSorting = true and OnSorting="GridView_Sorting". But when I click on the header to sort the the content of that column, it does not enters on my OnSorting="GridView_Sorting" it goes right to the GridView1_RowCommand why ?
Sometimes it just give me this error:
Object reference not set to an instance of an object error
Here's my Code:
<asp:GridView ID="GridView1" runat="server" AutoGenerateColumns="False" style="font-family: Verdana, Arial, Sans-Serif;"

This code return the error "System.ArgumentOutOfRangeException". I know this error but my gridView have 13 columns and I read the column 2 and 4 so I don't understand...
Only e.Row.Cells[0] works so I can't read the other columns.
I looked on the forum but I can not find my problem. Often this problem is due to the fact that the person tries to read a column that does not exist, this is not my case.
protected void grd_accident_RowDataBound(object sender, GridViewRowEventArgs e)
{
//Check CM
if (e.Row.Cells[1].Text.Equals("false"))
{
e.Row.Cells[1].Text = "<span class='glyphicon glyphicon-remove' aria-hidden='true'></span>";
}
else
{
e.Row.Cells[1].Text = "<span class='glyphicon glyphicon-ok' aria-hidden='true'></span>";
}
////Check HSE
if (e.Row.Cells[3].Text.Equals("2"))
{
e.Row.Cells[3].Text = "<span class='glyphicon glyphicon-remove' aria-hidden='true'></span>";
}
else
{
e.Row.Cells[3].Text = "<span class='glyphicon glyphicon-ok' aria-hidden='true'></span>";
}
}

I found the solution, I removed AllowPaging="True" on from the properties of GridView. It works now
I have an <asp:ButtonField> inside a gridview. How do I target the button in the gridview to make it Visible on runtime based on a condition ? I am not able to target it since it doesnt have the ID property. I am stuck here. Here is the code below
<asp:GridView ID="OrdersDataList1" runat="server" DataKeyNames="OrderID" Width="100%" SkinID="Gridview" OnPageIndexChanging="orders_PageIndexChanging"

PS I have the onrowCommand set on the gridview to listen to button click in gridview
You need to create RowCreated event for the gridview example
Before the GridView control can be rendered, a GridViewRow object must be created for each row in the control. The RowCreated event is raised when each row in the GridView control is created. This enables you to provide an event-handling method that performs a custom routine, such as adding custom content to a row, whenever this event occurs.
protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
{
}
OR
<asp:GridView runat="server" ID="GV1" AutoGenerateColumns="false">
<Columns>
<asp:BoundField DataField="Name" HeaderText="Name" />
<asp:BoundField DataField="Age" HeaderText="Age" />
<asp:TemplateField>
<ItemTemplate>
<asp:Button runat="server" Text="Reject"
Visible='<%# IsOverAgeLimit((Decimal)Eval("Age")) %>'
CommandName="Select"/>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
protected Boolean IsOverAgeLimit(Decimal Age) {
return Age > 35M;
}
Reference example
You can use the RowCreated event in the GridView as follows:
protected void GridView1_RowCreated(object sender, GridViewRowEventArgs e)
{
Button btn = (Button) e.Row.Cells[12].Controls[0];
if(1==1)
{
btn.Visible = true;
}
}
((BoundField)grv_selec.Columns[1]).DataFormatString = "{0:N2}";
I have a GridView with checkbox, dropdown and button as templatefields.
On button click I have to update the entire row in the data base.
This is my aspx:
<asp:GridView runat="server" ID="Gdv" AutoGenerateColumns="False" Font-Size="Small" CssClass="grid" BackColor="White" BorderWidth="0px" CellPadding="4" Width="100%" AllowSorting="True" SkinID="GVSalesManager" GridLines="none" AllowPaging="true" PageSize="10" PagerStyle-ForeColor="#0066cc" PagerStyle-CssClass="gvPagerCss" PagerStyle-Font-Underline="true" PagerStyle-Wrap="true"

</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
This is the updatebutton event
protected void BtnUpdateRow_Click(object sender, EventArgs e)
{
Button btn = (Button)sender;
GridViewRow grow = (GridViewRow)btn.NamingContainer;
//btn.
CheckBox chkbx = (CheckBox)grow.FindControl("chkRow");
if (chkbx.Checked != true)
{
labelErrormessage.Visible = true;
labelErrormessage.ForeColor = System.Drawing.Color.Red;
labelErrormessage.Text = "Please Check/Uncheck the CheckBox and Click Update";
return;
}
else
{
/*--Code to update the row's record in the edatabase.--*/
??
labelErrormessage.Visible = true;
labelErrormessage.ForeColor = System.Drawing.Color.Green;
labelErrormessage.Text = "Updated Succesfully";
return;
}
}
How do I read the row in which the button has been clicked and update its dropdownlist selected values in the database?
If you have some sort of identification data displayed in the gridview you could get the value from the row's cell like this grow.Cells[0].Text then find the record in the database and update its values.
You could also hide the id for example if this is information you dont want to show to the user. The row will still be located at index 0 but hidden.
Sample:
else
{
var record = queryDatabase(grow.Cells[0].Text);
//update record values
updateRecord(record);
labelErrormessage.Visible = true;
labelErrormessage.ForeColor = System.Drawing.Color.Green;
labelErrormessage.Text = "Updated Succesfully";
return;
}
I have a custom gridview and I use that grid in too many pages and I want to set the SortExpression text for all columns inside that grid in code behained ; as you see in the following code I have do that by overriding the OnRowDataBound eventhandler .
The problem is I can't access the evaluated datafield expression text ("START_WORK_DATE" in my case) for template Fields like what I did in BoundField

{
for (int i = 0; i < this.Columns.Count; i++)
{
if (this.Columns[i] is BoundField)

this.Columns[i].SortExpression = ((BoundField)(this.Columns[i])).DataField;
}
}
else if (this.Columns[i] is TemplateField)
{
// ???
}
}
}
}
You can do some thing like this. Set a header template with link button.
<asp:TemplateField>
<HeaderTemplate>
<asp:LinkButton ID="LinkButtonEmpName" runat="server" Text="Employee Name" CommandName="Sort" CommandArgument="Employees">
</asp:LinkButton>
</HeaderTemplate>
<ItemTemplate>
<asp:Label ID="LabelEmployee" runat="server" Text='<%# Bind("Employees") %>'/>
</ItemTemplate>
<FooterTemplate>
<asp:TextBox ID="TextBoxEmployee" runat="server"/>
</FooterTemplate>
And in row command event find command like this.
protected void grd_RowCommand(object sender, GridViewCommandEventArgs e){
if (e.CommandName.Equals("Sort"))
{
FilterExpression = e.CommandArgument.ToString() + " LIKE '%" + txtCaseNumber.Text + "%'";
BindGridView();
}}

I have a gridView which works nicely until I open a new window by clicking a button. When the new window is opened the values in one of the columns 'lblTotalPrice' gets erased. 'lblTotalPrice' is a template field, which is calculated in MealList_RowDataBound (quantity * price). The footer for the column, however is not affected when the new window is opened (also gets its value in MealList_RowDataBound).
Also the font-size of the data-bound columns are changed when the new window is opened.
Any ideas of what might cause this? When stepping through the code there are no other lines executed after btnEnvComment_Click
When gridView is databound again, everything is back to normal.
The gridView:
