C# - Access Label In Footertemplate Of Gridview In Javascript?
Oct 22, 2010
I have a label in a footertemplate of a gridviewcolumn. I want to put a calculated value (total of the rowvalues) in this label in javascript. I can access all the textboxes in my Itemtemplates, but I don't know how to find my label in my foortertemplates.
- I have a GridView , I want add a row FooterTemplate to add a new record in GridView . But I want to validate TextBoxs in FooterTemplate. My language I using is C# , Web Form .
I have two dropdowns in the footertemplate of my gridview inside a usercontrol.
I also have a button "btnADD" inside the footer template. I am using the footertemplate to add a new row to the grid.
What do I do to validate on Button_click event for 'btnAdd' if a value is selected in the dropdown other than "select.." which I dynamically add in rowdatabound event?
I have this javascript function that I wanted to implement, but it gets called in the Page_load event rather than the button click event and gives an error.
The javascript function that I need to call is this: ( I created a method to return a string to use it in regards to RegisterClientScriptBlock, but do not know exactly how to use it)

I have a column that I don't want to display but I still want to access its value. the other problem is that I can't access the value of a cell because it contains a label. Does someone know how to access the text in that label?

I have a javascript function that I am trying to validate the inputs of a gridview. My problem is that I cannot get the value of the cell. Here is what I have:
function fcnCheck() { var grid = document.getElementById("<%= GridViewProducts.ClientID %>"); var cellPivot; [code]....
This line does not work: cellPivot = grid.rows[i].cells[0];

I want to change the font size of my gridview in javascript because i am creating a printable version. How can I change the font size in javascript for the gridview?
I am trying to get access the elements inside gridview by validating this requirement: if checkbox is checked then 1) Role must be selected from the dropdown 2) And the Title textbook must be filled. I am getting this error now:
Error: Sys.WebForms.PageRequestManagerServerErrorException: Object reference not set to an instance of an object.
JS
<script type="text/javascript"> function validate() { var flag = true; var gridView = document.getElementById('<%= gvTest.ClientID %>'); for (var i = 1; i < gridView.rows.length; i++) {
I have Template fields configured for Gridview. The gridview is using an objectdatabsource to bind itself. I have the gridview configured to use Templatefields which then contain tables to display the information. This works fine.
My question is, is it possible to change the text of the label if certain criteria is reached. If "NumberOfDwellings" is 1 then change the label to read, "1 Dwelling". Where-as if NumberOfDwellings has more than one then it's "3 Dwellings".
So as the footer is writing programmatically, I would like to hide the FooterTemplate for somebody who use the custom repeater.. I was thinking [PersistenceMode(PersistenceMode.InnerDefaultProperty)] will do that but apparently not..
I am placing a dropdown list in the footer of a DataGrid like this:
[Code]....
In my code behind file, in the myDDL_OnLoad event handler, I call to the database, populate a SqlDataReader, and set the DDL's datasource to that datareader. I define what data columns should be used for the DataValueField and DataTextField of the dropdownlist. Then I call the DropDownList's DataBind() method. Everything works without error. But, when the dropdownlist is displayed, it has blank lines in it.
By that, I mean if 8 records are loaded into the dropdownlist, it will expand to a size appropriate for 8 rows but, it will be empty. there is no text in it.
Has anyone seen this type of behavior before? This dropdownlist is in the footer of a dynamically loaded ajax update panel so, it is difficult to see the source code to see what values are in the html element rendered to represent the dropdown.
I have a nested repeater which displays a food menu - e.g.
Sub Heading - Food 1 - Food 2 - Button 1
Another Heading - Food 1 - Food 2 - Button 2
etc. etc.
What I have is a series of buttons inside the itemtemplate of the parent repeater (button 1 and button 2) which, when clicked, i need to somehow add a new blank textbox to below food 2 in whichever section it is clicked
I am having trouble doing this. See my code snippet below:
[Code]....
When I run this though, I receive an error of "object reference not set to an instance of object..."
Do I need to actually find a control within the footertemplate itself?
