C# - Javascript Validation Inside Gridview Cell?
Nov 13, 2010
I have a single entry master with country name in a gridview . I have to edit the data in a grid view in asp.net c#. I want to validate the textbox inside edit template to see if the user enters invalid characters. I want to validate that using simple javascript code.
I tried [a-zA_Z] in regular expression validator...it is causing slow down in my app. so i am prefering JS.
I tried to get the value of client id using row data bound event in c# but it is interrupting the work flow of the program. :(

function fcnCheck() {
var grid = document.getElementById("<%= GridViewProducts.ClientID %>");

This line does not work: cellPivot = grid.rows[i].cells[0];

So I have a gridview control and I am binding it's datasource dynamically base on a dropdownlist. The gridview contains autogenerated columns with auto generated edit buttons. The datasource binded to the gridview is IQueryable<T> where T will be different for different datasource.
My detail problem is below:
A GridView binded to datasource dynamically with all autogenerated columns. When user click edit link, it will display value in autogenerated textboxes.
When user click update link, I am able to capture the user entered value in the textboxes in RowUpdating event, then pass those values to Linq update function to update the database. Now, the problem begin when I try to dynamically add validation controls to each editing row. In RowDataBound event, I am checking the editrowindex then adding validation control to gridview cell and pointing to cell.controls[0] which is the textbox control when the row is in edit mode, I am dynamically setting the textbox control id so that the validation control can set controltovalidate property. The validation control works, but the updating function is setting everything on the grid to empty string.
I am check the textbox text value in the loop, which returns "" for all cells except the id column. It was returning the correct value before I add the validation control. I guess since I added the validation control on rowdatabound event, will it rerender it's own autogenerated textbox in edit mode so that the text value of textbox no longer available in rowupdating event?
Is there a better or correct way to get the cell textbox value? I am using ((TextBox)dc.Controls[0]).Text where dc is DataControlFieldCell in rowupdating event.

I'm having a weird problem where the GridView cell that I'm programmatically updating turns grey, and throws a null error when attempting to save row. I have been searching all day and have not been able to find a solution. I'm guessing there is a problem with my code, so here it is:
Protected Sub Button1_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles Button1.Click

How can I disable the code behind validation when javascript validation is present? Then if there is no javascript enabled then the code behind validation will do its thing. What I notice is that it's reading the code behind valdiation not the javascript.

I have a GridView, the first column it's a RadioButton template and the second it's a DropDownList Template, the number of rows depends on the user, I mean they are not static. I'm using the following JS function to get the row selected with the radiobuttons:
[Code]....
With this function I know which RadioButton was selected, now, I would like to get the DropDownList value or text of the selected row, I know I have to loop through every DropDownList to get an array of controls, but since they are something like ctl00_ContentPlaceHolder1_GVProducts_ctl02_DValsDropDown, I just don't know how to achive this through JS.
