TextBox and Dropdown in a GridView
Sep 25, 2018 07:27 PM|Sam Solomon|LINK
Dear all,
I have textbox and dropdownlist in a nested gridview . When a Gridview loads I want my save button be disabled. It only gets enabled if any textbox is not empty or any dropdownlist value is greater than 0 . Below is my code
<asp:GridView ID="GridView1" AutoGenerateColumns="False" runat="server" ShowHeader="False" Style="width: 100%; border-width: 0px;">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:GridView AutoGenerateColumns="false" ID="GridView2" runat="server" ShowHeader="true" GridLines="None">
<Columns>
<asp:TemplateField>
<ItemTemplate>
<asp:TextBox ID="txtAmount" runat="server" ItemStyle-HorizontalAlign="center"></asp:TextBox>
</ItemTemplate>
</asp:TemplateField>
<asp:TemplateField>
<ItemTemplate>
<asp:DropDownList ID="dropAmount" runat="server" ItemStyle-HorizontalAlign="center"></asp:DropDownList>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
</ItemTemplate>
</asp:TemplateField>
</Columns>
</asp:GridView>
<asp:Button ID="btnSave" runat="server" Text="Save" OnClick="btnSave_Click" />

Rather than providing requirements and basic markup, post sample code that reproduces the issue and include the DB schema with data. Provides the steps to reproduce the issue, the expected results, and actual results,.

Hi Sam Solomon,
If you want to validate using jquery,you could try the code below.
<asp:Button runat="server" Text="save" ID="save" /> <script> function validate() { var flag = false; //check all the textbox ans dropdownlist $("#GridView1 table input[type=text]").each( function () { if ($(this).val() !="") { flag = true; } } ) $("#GridView1 table select").each( function () { if (parseInt($(this).val()) > 0) { flag = true; } } ) return flag; } $( function () { if (!validate()) { $("#save").prop("disabled", true); } else { $("#save").prop("disabled", false); } // bind blur event to check $("#GridView1 table input[type=text]").blur( function () { if (!validate()) { $("#save").prop("disabled", true); } else { $("#save").prop("disabled", false); } } ) //bind change event to dropdown to check $("#GridView1 table select").change( function () { if (!validate()) { $("#save").prop("disabled", true); } else { $("#save").prop("disabled", false); } } ) } ) </script>The result.
Best regards,

Hi Sam Solomon,
You should ensure the jquery selector select element correctly in you case.
$("#GridView1 table input[type=text]") $("#GridView1 table select")#GridView1 will choose element with id GridView1 . table will choose element with tag name table. input[type=text] will choose input of type text.
"#GridView1 table" will choose table in the element with id GridView1 .
Please choose your own textbox and dropdownlist.
Best regards,
Ackerly Xu

Hi Sam Solomon,
By "Please choose your own textbox and dropdownlist " , I mean your html structure is different from mine. So , for example, my selector $("#GridView1 table input[type=text]") could choose all the textbox in the second gridview while it may be not the case in your html.
So you should modify my selector according to your own html structure.
You could try code below
<script> function validate() { var flag = false; //check all the textbox ans dropdownlist $("[id*=GridView1] [id*=GridView2] input[type=text]").each( function () { if ($(this).val() !="") { flag = true; } } ) $("[id*=GridView1] [id*=GridView2] select").each( function () { if (parseInt($(this).val()) > 0) { flag = true; } } ) return flag; } $( function () { if (!validate()) { $("#save").prop("disabled", true); } else { $("#save").prop("disabled", false); } // bind blur event to check $("[id*=GridView1] [id*=GridView2] input[type=text]").blur( function () { if (!validate()) { $("#save").prop("disabled", true); } else { $("#save").prop("disabled", false); } } ) //bind change event to dropdown to check $("[id*=GridView1] [id*=GridView2] select").change( function () { if (!validate()) { $("#save").prop("disabled", true); } else { $("#save").prop("disabled", false); } } ) } ) </script>Please replase all the GridView1 with the id of your first gridview and replace all the GridView2 with the id of your second gridview. You should also change all the save with the id of your save button.
If it still doesn't work , you could write console.log($("[id*=GridView1] [id*=GridView2] input[type=text]")) in you script to see whether the selector choose the textbox in your second gridview.
Please click F12 and click the console option.If its length is 0 , that is to say the textbox is not chosen.

Ackerly Xu
