Add AutoPostBack To RadioButton In Gridview That Is Inserted As A Literal?
Feb 21, 2011
I have a gridview with a RadioButton column, which I am creating as per the following article:
[URL]
[Code]....
However - I want the form to Post Back every time the radio button is changed, as opposed to having to click a button to "submit".
As the radio buttons here are not .net controls, but standard HTML radio buttons, I'm not sure how I can do this.

I have been working on this issue for ever. I did not come to see any solutions for my problem with the gridview autopostback. I have around 10 fields (bound columns) and 1 template field (a checkbox) in my gridview.All the fields should become editable when a user clicks on the "Edit" of the gridview.After that when the user checks or unchecks the checkbox, depending on that two other bound fields should become editable or uneditable.Please help me.My code is as below:
AuctionDates.aspx.cs:
public
void HasJrMembers_CheckedChanged(object sender,
EventArgs e)

I have an gridview with 3 columns. As default I entered for each columnns an headertext, but depending on an language parameter in the data the headertext is changed on page_load with a SetLabels function.
Recently I added an templatefield textbox with an autopostback=true and an ontextchanged event :
When a user changes the text in the textbox all events are executed properly BUT my headertext is set back to the default value (from the .ascx) even tho page_load event is executing properly WITH the SETLABELS function.

I have a page that contains a GridView with a LinkButton, in a template column, that selects a row.
<asp:LinkButton runat="server" CommandName="Selecionar" CommandArgumento='<%# Eval("Id") %>'>
How can I do this with a RadioButton? I'd like so that when a user selects the radiobutton, my grid would execute the RowCommandEvent. Is there a way to accomplish this?

<asp:TemplateField HeaderStyle-Width="10%" ItemStyle-Height="30px">
<ItemTemplate>
<%-- It works with a linkbutton -->
<asp:LinkButton ID="lnkSelecionar" runat="server" Text="Selecionar" CommandName="Select" CommandArgument='<%# Eval("Id") %>' Visible="true"></asp:LinkButton>
<%-- i need a RadioButton =/ --%>
<asp:RadioButton ID="radioRole" runat="server" CommandName="Select" CommandArgument='<%# Eval("Id") %>' AutoPostBack="true" GroupName="Role" />
</ItemTemplate>
</asp:TemplateField>

After render group name comes in the name attribute with different name for each radiobutton in the gridview.
I tried to set all the names as same. But when we see the source in the browser it is unique.
How to change the name for all the radiobutton in the gridview as same.
protected override void Render(HtmlTextWriter writer)
{
System.IO.StringWriter sw = new System.IO.StringWriter();
HtmlTextWriter htw = new HtmlTextWriter(sw);
ase.Render(htw);
htw.Close();
string h = sw.ToString();
RadioButton first = (RadioButton)gvAddOption.Rows[0].Cells[3].FindControl("rblValue");
string uniqGroupName = first.UniqueID;
uniqGroupName = uniqGroupName.Replace(first.ID, first.GroupName);
foreach (GridViewRow row in gvAddOption.Rows)
{
RadioButton val = (RadioButton)row.Cells[3].FindControl("rblValue");
string eachGroupName = val.UniqueID;
eachGroupName = eachGroupName.Replace(val.ID, val.GroupName);
//h.Replace("name="" + eachGroupName + """, "name="" + uniqGroupName + """);
h.Replace(eachGroupName, uniqGroupName);
}
writer.Write(h);
}

I have a Gridview that provides the user the student name for a particular class, a dropdown list to enter grades. If a grade of 'U' is given, a textbox appears in which the last day of attendance must be listed.
It works... though not as conviently as it could; the faculty would like to be able to tab from one dropdownlist to next in succession.
On each ddlGrades changes I write the value to the database and if a 'U' was chosen, display the textBox... but I can't figure how to set focus on the next ddlGrades control, or even the same ddlGrades control that initiated the postbock.
Below is my simplified .aspx followed by the codebehind

In my gridview, I have a column for Amount. I want to calculate the amount as soon as user changes the Amount and display calculated Amount in a textfield. What I have done is I have Amount as Templatefield and have set Autopostback = true. In the event handler for textChanged I have function for calculate Amount which will calculate the amount and set the calculated value in a textbox. But I am getting an error message:
[NullReferenceException: Object reference not set to an instance of an object.]

I am currently binding my Detailsview and Gridview together by a "ID" field selectedvalue "1". Which works great except for the fact that I don't want the user to have to go down to the gridview and select the page and then the record to view it in the detailsview.
I have 1 sqldatasource for detailsview and another sqldatasoure for the gridview. Both have the exact same select statement.
I want the gridview and detailsview to automatically display the last record inserted not the first record in the table.

I have an object data source control. and to insert the control I add the object to the database then call databing on the gridview the DataSource control is bound to.
My question is - how would I know where the newly added row is? I can'y go by id, because the dbase creates the id.
I'm thinking maybe last data key, but based on the sort that would be accurate.

I want to add 2 radiobuttons into a column:
- Present
- Absent
There is also a field in the database: 'Present'
I have googled his topic, most of the answers provide with the .aspx code.
I would like to do it from the 'Design' method, ie. from the Property box.
If the user select 'Absent' then a dropdown list have to be 'visible' on the next column for selection.

In trying to improve 'user experience' with a GridView, I have an administrative application where a GridView is displaying records from a SQL table. One of the columns is a bit column, and is displayed as a checkbox in the GridView. I want the user to be able to simply check or uncheck the box while viewing the GridView, and the value in that column for that record is immediately updated. So I set AutoPostBack="true" on the CheckBox in the GridView's Template Field.
But tests are indicating that the column value is not actually getting changed, even though the page appears to post back and displays the newly checked (or unchecked) checkbox correctly. But if I check the SQL table directly the column's value has not changed.

I have a checkbox placed inside a gridview:
<GridView><asp:TemplateField HeaderText="Driver"> <ItemTemplate> <asp:CheckBox ID="CheckBoxDriver" AutoPostBack="true" OnCheckedChanged="GridView_Persons_SelectedIndexChanged" ValidationGroup='<%# Eval("ID") + "-" +((GridViewRow)Container).RowIndex %>' CssClass="CXDriver" runat="server" Checked='false' /> </ItemTemplate> </GridView>
For example: A listViewItem 1 has 3 drivers are checked, A listViewItem 2 has 2 drivers are checked.
Therefore, if changing the selectedIndex of the list, the checkbox indexChanged event will be fired.
How could I disable the autopostback of the checkbox during the listview item changed.

Does anyone knows how to add a radiobutton column into a dynamic gridview? The problem with the asp.net radiobutton is that in a grid view is not mutually exlusive so actually it would have to be a literal type= "radio "control, but how to add it when the gridview is created dynamially?
Also, once I have the radioButton set up correctly...how can I identified whether that row has the radiobutton checked or not?
