I have a gridview i want to know how to get data of gridview row on button click
protected void Button1_Click(object sender, EventArgs e)
{
GridView grd = (GridView)((Button)sender).NamingContainer;
string name = grd.SelectedRow.Cells[0].Text;
}
[Code] .....
I have Gridview in UpdatePanal but their is problem with template field
<asp:TemplateField HeaderText="EDIT">
<ItemTemplate>
<asp:LinkButton ID="lnkEdit" runat="server" ToolTip="Edit Unit" OnClick="lnkEdit_Click"
CausesValidation="False"><img src="IMG/screw-driver.png" alt="" /></asp:LinkButton>
</ItemTemplate>
</asp:TemplateField>
and link button click event is
protected void lnkEdit_Click(object sender, EventArgs e)
{
GridViewRow clickedRow = ((LinkButton)sender).NamingContainer as GridViewRow;
ScriptManager sm = (ScriptManager)Page.Master.FindControl("smanager");
sm.RegisterPostBackControl(clickedRow);
lblUnitID.Text = clickedRow.Cells[0].Text;
txtUnitName.Text = clickedRow.Cells[1].Text;
txtDecimal.Text = clickedRow.Cells[2].Text;
btnUnit.Text = "Update";
}
but text box value is not set but when we do it in PostBackTrigger is work.
can we do this AsyncPostBackTrigger.
The below is from the watch window in vs2010.
((sender as EntityTextBox).NamingContainer as GridViewRow).UniqueID "ctl00$cphMainFrame$PurchaseControl1$PurchaseFormView$PurchaseRowGridView$ctl04"
I need to loop through all the gridviewrows, and call a function for every row using the datakey. How do I get the datakey of each row?
My code looks something like:
foreach(GridViewRow gvr in GridView1.Rows)
{
DoSomething(gvr.INSERT DATA KEY OF THIS ROW HERE);
}
I have the DataKey value, I want to use that to get the GridViewRow and retrieve information from various columns - I see lots on information on how to get the datakey from a gridview row, but not the reverse.
View 4 RepliesMy head aches from beating it against the wall for so long. I have a gridview that is populated from a code behind table. The gridview has 3 bound lables, a checkbox (unbound) and another label (unbound). All fields are in template fields. I have coded a vb sub with one command: beep. It fires perfectly every time a user checks the gridview ckeckbox. Here are the columns of the gridview:
1. Player - bound label
2. Description- bound label
3. Amount- bound label
4. ToPay - ckeckbox
5. AmountToPay - unbound label
When a gridviewrow's checkbox is checked (or unchecked) the code determines the check status. If it is checked then the AmountToPay label is to display the same value of the third label (Amount) or it will clear it's text value if the checkbox is unchecking the box. Here is my code:
The gridview:
[Code]....
Here is the vb code that does beep():
[Code]....
I have tried about a dozen ways of reading the checked property of the checkbox but nothing works (sender, e, gridview, rows, items, cells, findcontrol, adnauseum). I want to work the code like this somehow:
If row.Checkbox.checkproperty=true then
set lblToBePaid.Text = the lblAmount.Text
Else
lblToBePaid.Text = ""
EndIf
What is the equivalent of gridviewrow to datagrid??
View 2 RepliesI would like that ID of subcontrol generated from the GridViewRow (NamingContainer) be named including database unique ID.
Exemple :
Suppose in the first colum of my GridView I have a Label displaying the name of an item fetch from a database table.
SQL Database table definition
SQLTable
- UniqueID
- Name
In this table I have the following records
- 1956 Hello
- 3013 World
- ... ...
Suppose I have a GridView having a label (id="lbName") in the first column template.
Now I'm binding GridView using this query : SELECT UniqueID, Name FROM SQLTable
After binding, the HTML result will be :
myGridView_ctl101_lbName
But I would like that NamingContainer names sub items like this :
myGridView_ctl1956_lbName
So I have tried in the RowDataBound event of the GridView : e.Row.NamingContainer.ID = (DataRowView)e.Row.DataItem)["UniqueID"].ToString()At first look it output exactly what I need but after that I can't get working Edit mode, it seem to break DataKeys or something else.
I add gridview row dynamically like that; After page postback some gridrow change and not visible.
protected void grv_RowDataBound(object sender, GridViewRowEventArgs e)
{
GridViewRow gvr = e.Row;[code]....

Which is pretty much eaxactly what I was after! . I have been trying to alter the edit functionality instead of actually having to click on an edit button the user can click anywhere on a selected row to bring up the edit popup window. I have been trying to figure this out for a couple of days and cannot find a way to get it going.

If in the coding before gridview databind, I have set the dataset ds to the gridview datasource.
And dataset ds which has more columns than columns in gridview shown and this gridview has checkbox in the first column.
If I want to get the value which is in the dataset ds which refer to the gridview with checkbox checked.
it should be what syntax?
grview["Data10"]?
I cannot use grview.cells, as these datas not shown in the gridview but refer to the gridview datasource dataset values.
Is there an easier way to erase the data from all controls in a gridviewrow than my current approach (code below)?
The problem: When a new type of control is added to the grid, like a radiobutton, it would not get handled here without adding to the code. The tests for type of control can get long and monotonous.
The solution I am seeking: Test the control once for "is WebControl". If it is a web control, cast it and call a single command that would erase its data. Does such a concept exist in ASP.NET 2.0/C#? I know I can do other things on the WebControl level, like set backcolor, but would like to do the same for erasing data.
foreach(Control c in row.Controls)
{
if(c is TextBox)
{
TextBox tb = (TextBox)c;
tb.Text = string.Empty;
}
elseif(c is CheckBox)
{
CheckBox cbx = (CheckBox)c;
cbx.Checked = false;
}
elseif(c is DropDownList)
{
DropDownList dd = (DropDownList)c;
dd.ClearSelection();
}
}
I have 4 checkboxes. I need that user should atleast select one checkbox and then submit the form. But the onClick event of the button is not working. I already have events for button click. See the code for reference.

<asp:CheckBox ID="chkInvestmentLoan" runat="server" CssClass="check" />
<asp:CheckBox ID="chkWarehouseReceipt" runat="server" CssClass="check" />

I have a gridview that is selectable. Below it I have a dropdownlist and a textbox. The dropdownlist has the options for each column in the row(I am using an ajax autocomplete extender that checks for related values in the textbox based of which dropdownlist value is selected.) I want to take that a step further and see if I can select a row based on what is in the textbox on the textchanged event. Right now im playing around with using a datatable and then filling a string[] of whatever column the dropdownlist is selected on.
protected void txtFilter_TextChanged(object sender, EventArgs e)
{
DataTable dt;
SqlCommand cmd = new SqlCommand("SELECT * FROM General", csbg2);
SqlDataAdapter da = new SqlDataAdapter(cmd);
dt = fillDatatable(cmd, da);
string[] items = new string[dt.Rows.Count];
switch (ddlEducation.SelectedValue)

I have a checkbox and a textbox in a GridView (for every row), and I'd like to be able to write some javascript that would enable and disable the textbox depending on the state of the checkbox (checked or unchecked). I guess I'd have to give JS the row index somehow.

I've created a databound gridview inside the gridview's RowDataBound I use the RowSpan property to merge cells. The grid ends up looking like this for example....
Data Data Data Button
Data Data Button
Data Data Data Button
Data Data Button
Data Data Data Button
The button is generated using a Template Field and is a standard ASP:Button. If I click a button in an unmerged row everything works as expected. If I click a button in a merged row...the sender object on the command comes back as null and no matter what I try I can't seem to fix it or get a reference to the button.
sender.CommandArgument
for example returns and empty string.
am designing report using gridview in which i want drill down report, i.e. when i click a cell of gridview which contains value from the database. i want a new gridview to be populated with detailed report, which should be generated by passing some values from parent gridview.
i have written some code for the same,but in the code the event is not getting fired.
code is:
in gridview rowdatabound
protected void gvHdr_RowDataBound(object sender, GridViewRowEventArgs e)
I have a lot of data to display in a GridView. Because there's so much information per row, I'd like to be able to display additional information when a user clicks on the row, so I thought a PopupExtender from the AJAX Toolkit would be perfect.
Ideally, I want the popup to display whenever any of the controls within the row are selected. I've been able to successfully attach the PopupExtender to a single control within the row, but I can't get the pop-up to attach to the row itself.
I would have thought that setting the PopupExtender's TargetControlId to the Row's ClientID within the RowDataBound event would work, but when I do this I get a runtime error:
TargetControlID of 'popupExtId' is not valid. A control with ID 'gvList_ctl02' could not be found.
I noticed that the GridViewRow is rendered, the tr element does not include an id, so I also tried extending the GridView control to override the CreateRow method to render the id - using this method I was able to render the row's ID (e.g. gvList_ctl02), but the same runtime error was thrown when I added the PopupExtender back into the code.
I also tried binding the showPopup() javascript command to the row's onclick event to get the popup to display manually; whilst the click event is registered OK and is definitely triggered, the popup is still not shown.
Does anyone have any idea how to / if you can bind a PopupExtender to a GridViewRow?
My row bound code is as follows:
protected void gvList_RowDataBound(object sender, GridViewRowEventArgs e)
{
if (e.Row.RowType == DataControlRowType.DataRow)
{
// Bind the popup extender's target ID to the row ID
// This will cause a runtime error
PopupControlExtender pop = e.Row.FindControl("popupExtId") as PopupControlExtender;
pop.TargetControlID = e.Row.ClientID;
// Also bind the client side click handler to try to get the popup to show
// The alert is triggered and no javascript error is generated, but the popup does not display
e.Row.Attributes.Add("onclick", "alert('Row Clicked'); $find('" + pop.BehaviorID + "').showPopup();");
}
}
