dim str as Integer
str=txtphone.text

Holds signed 32-bit (4-byte) integers ranging in value from -2,147,483,648 through 2,147,483,647.
My guess is the phone number is greater than this value. Use a long instead of int

try with this code.
Dim MobileNo As Int64 = 0
Try
If Not (txtMobile.Text = "") Then
MobileNo = CType(txtMobile.Text.Trim(), Int64)
End If
Catch ex As Exception
Response.Write(ex.Message)
End Try

Took you long enough to come up with this. Couldn't find it quickly in the book?
Actually you should use string.length to test for an empty string and try_parse to cast the string. I'll leave it up to you figure out why, if you can.

For itemcode, I am using dropdownbox which is populated with all code and new code option when user click new code option a newtextbox becomes visible. my problem is how can I make newtextbox mandatory field whenever new option field is selected(as it may left blank in case of edit option
And making requiredfield validator not workable ).

function SetValidation()
{
var ctl = document.getElementById('RequiredFieldValidator1');
if (document.getElementById('chAll').checked)
ValidatorEnable(ctl, false);
else
ValidatorEnable(ctl, true);
}
Note : Yes, You can use this function in the html source javascript section.
You have to use this function on any dropdownlist or checkbox onclick event.
This function will make requiredfield validator control enable/disable by javascript.
Hope you Enjoy it.
Regards,
Abhi

I add a asp Checkbox in the Datagrid ItemTemplate and HTML checkbox in Header Template.In the datagrid am loading the images and the path from the server folder.am loading all the images in the page load event.page load event as follows
if (!IsPostBack)
{
DataSet ds = new DataSet();
DataTable dt = new DataTable("Photos");
dt.Columns.Add("Photos", Type.GetType("System.String"));
foreach (string Files in Directory.GetFiles(System.Web.HttpContext.Current.Server.MapPath("Photos"), "*.jpg"))
{
dt.Rows.Add(Files);
}
ds.Tables.Add(dt);
this.dgPhotos.DataSource = ds;
this.dgPhotos.DataBind();
All the images am getting in the Datagrid.but my problem is,i want to delete the checked images.the delete code as follows
foreach (DataGridItem item in dgPhotos.Items)
{
CheckBox chkBox = (CheckBox)item.FindControl("chkItem");
if (chkBox.Checked)
{
File.Delete(item.Cells[2].Text);
}
}
while clicking the Header template checkbox it will select all the Item template checkbox[Javascript function],but the problem is i will not get the checked state in the delete event,getting checked=false.so i cannot delete the images.in the page load event if am not using !Postback and if i select one by one in the Itemtemplate checkbox i could delete,i will get checked=true but if select header check will not get.what is the problem.Is there any solution for this.

Can I peek into your Javascript code??
|
|
|
|

Javascript Code
function CheckAllDataGridCheckBoxes(aspCheckBoxID, checkVal)
{
re = new RegExp(':' + aspCheckBoxID + '$') //generated control name starts with a colon
for(i = 0; i < form1.elements.length; i++)
{
elm = document.forms[0].elements[i]
if (elm.type == 'checkbox')
{
if (elm.name=aspCheckBoxID)
{
elm.checked = checkVal;
}
}
}
}
|
|
|
|
|
check out if statement "if(elm.name=aspCheckBoxID)"

When you select the master check box will it checking all checkboxes in grid ?
|
|
|
|
|
while clicking the Master checkbox i could select all the checkbox,but when i click the delete button i won't get the sub checkbox value.
|
|
|
|
|
What code have you written to get the checked values?

Well usually this happens when viewstate of the grid is disabled. Make sure it is enabled. Now try getting your checkboxes like this
int DgItemCount = Datagrid.Items.Count;
for ( int i=0;i<=DgItemCount-1;i++ )
{
CheckBox chk = (CheckBox)Datagrid.Items[i].Cells[YourCheckBoxCell].FindControl(YourCheckBoxName);
if ( chk.Checked )
}

|
|
|
I used this code also eventhough am getting checkbox.checked=false;please check the first mail.i think the code everything is correct some property or something i have to do.

Depends which version of framework are you using. If using 1.1 I would suggest not to bang your head too much. If 2.0+, Master is included in the Framework itself.
